Hello, it's me Izebeq. I've checked on your submission.

1. Superimposed Line

• I can see you draw the lines confidently. Nice.

• The lines only fray at one side, which mean you planned the lines carefully. Good job.

2. Ghosted Line

• The lines are straight. Good.

• Few of them arch a little, but still ok.

3. Ghosted Plane

• Most of the lines are straight and confident.

4. Table of Ellipses

• You draw the ellipses 2-3 times as instructed. Good.

• The ellipses fit snuggly inside the border and you fill the empty space as well.

• Most of the ellipses drawn smoothly and confidently. Good job.

5. Ellipses in Plane

• You draw the ellipses 2-3 times as instructed. Good.

• The ellipses fit snuggly inside the border and you fill the empty space as well.

• Most of the ellipses drawn smoothly and confidently. Good job.

6. Funnels

• You draw the ellipses 2-3 times as instructed. Good.

• The ellipses touching the side of the funnel nicely.

• The ellipses also align well with the minor axis.

7. Plotted Perspective

• You use ruler as instructed. Good.

• The horizontal lines are perpendicular to the horizon. Good.

• The edges plotted toward the VPs correctly.

• Also good job with the hatching. Draw the hatching using your shoulder and ghosted method help you improve faster.

8. Rough Perspective

• You work with 1 point perspective as instructed.

• The front and back faces are rectangular as intructed.

• Most of the extention lines heading toward the VPs, good job.

• Some of the boxes are crooked. You can try to ghost few time while estimating.

9. Rotated Box

• You followed the given instruction. Good.

• The gaps between the boxes are tight and consistent. Good.

• It seems like your unsure about how the VPs work as some of the boxes are not rotating. You'll explore more about it in the 250 boxes challenge. I'll drop this for future reference https://drawabox.com/lesson/1/rotatedboxes/notrotating

• you draw through the boxes as instructed. Good job.

• You also draw all the boxes.

10. Organic Perspective

• You use ghosting method as instructed.

• some of the boxes are wonky, but I believe you will tackle this as you do the next challenge.

Overall I think you've done well and will tackle your weakness as you go through the boxes challenge. I'll mark you homework as complete. If you find any of this unclear, you can ping me (@izebeq) in lesson 1 channel.

Good luck with the 250 boxes challenge.

Hello MORIF! I'm Aamon and I'll be reviewing your homework.

Good job on completing Lesson 1! Starting is the most important step.

LINES

• Superimposed Lines

  • Good! Normal amount of fraying for this stage, and your lines are confident.

• Ghosted Lines

  • You overshot quite a bit here, but your lines show improvement in the following exercises.

• Ghosted Planes and Ellipses

  • Good job.

  • Note: You didn't need to re-do the ghosted planes, you are meant to draw the ellipses in them and just send it like that.

Ellipses

• Tables of Ellipses

  • There are areas where the ellipses either overlap or have empty space between them, but it's pretty minimal.

  • The rest is ok!

• Funnels

  • Again, a few errors in alignment or overlapping here and there, rest is good.

Perspective

• Plotted Perspective

  • The plotting is fine, but there are a few issues with the hatching. Firstly, make sure it's consistent, you have areas in which you did it with a lot of space between the lines and the rest in tighter spacing. Secondly, you have areas where the hatching of a box that appears to be in the back of another is shown on top.

• Rough Perspective

  • All good, there are a few places where you extended the lines incorrectly, but i see you've corrected yourself.

• Rotated Boxes

  • You have too much spacing between the boxes, make sure you keep them very close to one another.

  • You drew more boxes than you should have, please read the instructions carefully before doing an exercise.

  • Note: overall it looks pretty asymetrical, it's helpful to do similar steps at the same time, i.e. first do the boxes neighbouring the center one on the vertical and horizontal axis, then after you're done with that do all the boxes neighbouring the center one on diagonals and so on. This way, when you draw a box, you can use it as a guide to draw other ones.

• Organic Perspective

  • Lines are good.

  • You should have drawn a bit more boxes, and in a few instances you have a box that is bigger than it should be. In this exercise all the boxes are roughly the same size, but because of perspective we draw the ones that are further away as smaller, so make sure this stays consistent. Also, not only do the boxes go smaller the further they are, but also the space between them looks smaller (assuming they're all supposed to be the same distance one from another in a row). If you apply these tips the perspective will be a lot more clearer.

  • The boxes that are closest to the viewer are supposed to have more dramatic foreshortening, but yours don't really have any.

Conclusions

Overall, good job! A lot of people don't even get to finish the first lesson. Before moving onto the 250 Boxes Challenge, I would advise to redo the Rotated Boxes exercise because you didn't follow the instructions properly, and also a page of Organic Perspective.

If you have any questions or feel stuck don't be afraid to ask! You can reply here or join the Drawabox discord server if you haven't, it's very helpful.

Hello Chieftang, just dropping by to give you some feedback on your bugs. This might be a tad shorter than my usual critiques, but that’s mostly because you’ve done such a good job that there isn’t much to criticise.

Starting with your organic forms you’re doing a good job of keeping your lines smooth and confident, and sticking to the characteristics of simple sausages that are introduced here.

Your contour curves are looking confident and well aligned too, and it is nice to see that you’re experimenting with shifting their degree. As a little bonus I’d like to share this diagram with you, showing the different ways in which our contour lines can change the way in which the sausage is perceived. You’re doing great at expressing your forms in a variety of orientations, the point I wanted to make here is that when one end of a form faces the viewer the degree of your contour lines should be shifting wider as we slide along the sausage form, moving farther away from the viewer. This is also influenced by the way in which the sausages themselves turn in space, but farther = wider is a good rule of thumb to follow. I think perhaps you’ve understood that already, as I saw you shifting them correctly on the form at the bottom of this more recent image.

Moving on to your insect constructions your work is similarly well done. I can see you using the methods shown in the demos, sticking to the principles of markmaking (smooth, confident purposeful lines) and the principles of construction (starting with simple solid forms and building your construction up gradually piece by piece) and there is a fair bit of growth across the set.

I can see that you’ve put a fair bit of thought into how your forms exist in 3D space, and how to connect them together with specific relationships, and your constructions are coming out quite solid and convincing as a result.

You’re very much on the right track, although I am going to go ahead and use a piece of prewritten text that I share with many students to help them to build up their constructions in 3D more consistently.

Because we're drawing on a flat piece of paper, we have a lot of freedom to make whatever marks we choose, but many of those marks would contradict the illusion you're trying to create and remind the viewer that they're just looking at a series of lines on a flat piece of paper. In order to avoid this and stick only to the marks that reinforce the illusion we're creating, we can force ourselves to adhere to certain rules as we build up our constructions. Rules that respect the solidity of our construction.

For example - once you've put a form down on the page, do not attempt to alter its silhouette. Its silhouette is just a shape on the page which represents the form we're drawing, but its connection to that form is entirely based on its current shape. If you change that shape, you won't alter the form it represents - you'll just break the connection, leaving yourself with a flat shape. We can see this most easily in this example of what happens when we cut back into the silhouette of a form.

Fortunately I didn’t notice any areas where you’d cut back inside the silhouette of forms you had already drawn, and that’s fantastic. While cutting back into a silhouette is the easiest way to depict the issues with modifying a form after it's been drawn, there are other ways in which we can fall into this trap. For example I’ve marked with blue on a section of your moth a couple of spots where you drew a one-off mark bridging from one 3D structure to another, enclosing the hatched area. But this hatched area exists only in two dimensions - there is no clearly defining elements that help the viewer (or you, for that matter) to understand how it is meant to relate to the other 3D elements at play. Thus, it reminds us that we're drawing something flat and two dimensional, and in so doing, reinforces that fact to you as you construct it. While extending the silhouette of leaves or insect’s wings with single lines works fine, this is because they are paper-thin structures, so essentially they are already flat and altering their silhouette won’t flatten them further. When we want to build on forms that aren’t already flat we need to use another strategy.

Instead, when we want to build on our construction or alter something we add new 3D forms to the existing structure. Forms with their own complete silhouettes - and by establishing how those forms either connect or relate to what's already present in our 3D scene. We can do this either by defining the intersection between them with contour lines (like in lesson 2's form intersections exercise), or by wrapping the silhouette of the new form around the existing structure as shown here.

This is all part of understanding that everything we draw is 3D, and therefore needs to be treated as such in order for both you and the viewer to believe in that lie.

I’m really happy to see that you’re already exploring this kind of additive 3D construction quite liberally in some of your pages, your mantis and crab have some really good examples.

The next thing I wanted to talk about is leg construction. It looks like you tried out a few different strategies for constructing legs, but I’m happy to see that you were using the sausage method for your later constructions and getting the hang of applying it well.

It's not uncommon for students to be aware of the sausage method as introduced here, but to decide that the legs they're looking at don't actually seem to look like a chain of sausages, so they use some other strategy. The key to keep in mind here is that the sausage method is not about capturing the legs precisely as they are - it is about laying in a base structure or armature that captures both the solidity and the gestural flow of a limb in equal measure, where the majority of other techniques lean too far to one side, either looking solid and stiff or gestural but flat. Once in place, we can then build on top of this base structure with more additional forms.

I’m happy to see that you’ve taken a swing at building onto your sausage armatures on many of your pages, adding the sorts of lumps, bumps and complexity that you observe in these structures, arriving at a more characteristic representation of the leg in question than what can be achieved with the sausages alone. I have some diagrams to share with you that I hope will help you to build onto your leg structures “in 3D” as you move forwards.

• These diagrams show how we can add to the construction with complete 3D forms instead of flat shapes and one-off lines.

• This diagram shows how instead of fully engulfing an existing form within a new one, we can establish a clearer relationship between the existing form and the new addition by breaking it into two pieces.

• This ant leg demo shows how we can take the sausage method and push it further, adding all kinds of lumps bumps and spikes to the sausage armature.

• I’d also like to share this dog leg demo with you, which shows how the sausage method can be applied to animal legs. This is important, as we’d like you to continue to stick with the sausage method of leg construction when tackling your animals in the next lesson.

If a part of your construction won’t fit on the page, such as some of the legs of this spider you can retain the solidity of these forms by capping them off with an ellipse, rather than running them off the page as a pair of lines and leaving them open ended. You will see Uncomfortable using this technique in the tail of his “running rat” demo on the informal demos page of lesson 5.

Before I wrap this up I should touch briefly on texture. I think that the texture you added to your tick is excellent. You’ve told the viewer that the exoskeleton has little pits or holes along its surface, implicitly, by drawing cast shadows rather than outlining the holes themselves, great job. The texture on your moth was a little less in line with what the texture section of lesson 2 describes. I suspect you filled in the eye because it looked dark in the reference, rather than because it is sitting in cast shadow. This gives the eye the look of a flat shape or a hole, rather than that positive bulging form I’d expect from a bug’s eye. The detail on the wings is also looking a bit explicit as you seem to be outlining a pattern, rather than describing a texture.

Anyway, overall you’ve done an excellent job with this lesson and I’ll tag it as complete. You’ll need a couple of agrees to trigger the badge, but I don’t expect you to have any difficulty getting them.

Hello I'm Simon and will be reviewing your Lesson :)

First of all congrats on completing the 250 Boxes challenge! It's a really hard part of the course and having completed it Lesson 2 will feel much easier so have fun with it!

General notes

Be careful you extended your lines in the wrong direction a few times (boxes n°6,9,26,27...) make sure to keep an eye on that next time you do boxes, if you struggle to know in which direction to extend them you just have to think of extending your initial Y, and if you still struggle to with that technique don't hesitate to ask for help I'll try to help as well as I can :) You seem to have some diverging/parallel lines (like n°57, 95) that's okay just make sure to keep an eye on that and for the next time you'll pull the boxes exercise as a warmup. I encourage you to focus on practicing those shallower foreshortening boxes which are tougher but will help you improve a good deal! No wobbly lines in sight, good job. A few times (boxes93-97, 99) you seem to have went over your line again, that's not great, moving forward please try to not do that no matter how important you think this line is to the drawing, drawing over your line makes your drawing look messier, even if you make the new line perfect, and it also hinders your ability to remember your mistakes since you try to hide it under a new line, so it's not a big deal here but with the next few lessons be sure not to do that :) Good job on varying the orientation of all your boxes! That helps you improve much faster and you did well to do it! Great job on having your inner corners really good! Even for the last boxes it's often really hard to get a back corner that's consistently good but you managed. Well done!! You started using hatching on your boxes, that's a good habit, so keep practicing that on the next lessons when you can, that will already give you a little head start :) For your next boxes in your warmups I recommend you start using lineweight to emphasize the weight and volumes of the boxes and to bring them to the next level, it's a good skill to have that will come in useful in later lessons!

Other notes

I don't really have anything to add that I didn't say before, though I'd like to point out that your improvement from the first to the last boxes is very visible, I hope when you look back on that exercise you can too see it because your last boxes feel so much more solid than those first ones this month of work was really useful and will help you tackle the next lesson's problem better!

So I'll be marking your exercise as complete Good luck moving forward!

Also I strongly encourage you to go review some submissions on the website :) You can easily review some lessons 1 and if you feel like it can review 250 boxes or wait until you completed lesson 2! Don't hesitate to do a review every so often. It really benefits you so you don't forget the point of the previous exercises and helps other people who are waiting on a review :)

Hello Heiwa I'm Simon and will be reviewing your lesson!

Organic forms

So it was supposed to be two page of contour curves and not one of ellipses and the other of curves, I'll ask of you to do the second page of contour curves since I know that shouldn't take long :) Don't worry that will be the only revision

Your forms are really good! You are experimenting with the shape the twists and always manage to fit those curves snuggly between each side so really good job on that! I don't have much to add, keep doing warmups before working each time and that's all :)

Insects constructions

I completely understand your worry of feeling rusty but these insects look great!

I think the little "rough work" on that first page is really great and helped you understand some of those 3D forms so I strongly recommend for your next lessons you keep doing little studies like that I'm sure it'll really help!

The volume on most of these are good, great on some like 4 where you can really feel that with all those little studies you really understood the volume of that bug (6,8,11 i also don't have anything to add on them) . For the others I think they work like the fly 5 and 2 are okay but some of those curves that are supposed to give that sense of volume kind of break it a little, so make sure to be really focused for those little bugs that don't have much volume cause very often they'll be the hardest to do since you don't have many lines to work with. I'd have liked to see you work on some of the bugs' legs but that's not a big deal, if you want you can add drawing bugs to your warmups pool and next time you do it you can try to tackle some of those smaller details.

Finally if I could give you a little tip i think you'd benefit taking more time to look at your reference, for n°7 and 9 they're not so complex creatures but you don't have many volumes to work with, so you really want to take the time to look at those basic volumes, maybe put some dots down on your page to make sure you get the proportions right and then do a few curves to give the volume. On n°9 I feel like you may have lost your patience, or weren't in it too much cause some lines are just put flat on top, without being drawn confidently and without wrapping around the edge, and since all the lines on the volume are like that the creature just feels like it's flat where as 11 as a great sense of volume (and some really nice texture too).

So when you get frustrated, take a break, or do some volumes for the legs before trying to rusht the contour curves that could ruin the volume of your drawing.

I think that's about it, I hope that was helpful!

Don't forget to send the second page of sausage forms with contour curves and I'll mark your lesson as complete!

Hello Grumbo, I'm Simon and I'll be reviewing your lesson 1!

Lines

Good job not much to add, you drew them with confidence and took your time with each stroke

The curves are also well done, don't hesitate to try even more complex shapes when you do that exercise again as a warmup!

Ghosted lines

They are once again drawn with confidence and have little no no wobble to them so good job! You even hit the dot on some and remain close to the mark each time so that already puts you on a good level.

Ghosted planes

Same again, some lines in the middle of your planes are a little more wobbly like the one dead center of the page so keep an eye on it next time you do that exercise.

Ellipses tables

You did a good job of drawing through your ellipses and of fitting them really snuggly together, this is a really hard exercise and you managed to keep your ellipses very constant so good job again!

Ellipses in planes

For the ellipses in your planes they're a little worse than the table ones, some don't touch a single side like the one at the bottom right corner, and some are really not evenly shaped, I recommend you keep practicing your ellipses through that exercise primarily and you first of all focus on drawing your ellipses round and with confidence.

Funnels

On the other hand, your funnels are great, you even seem to have tried to make the angle of your ellipses bigger on one and it works really well, your first page looks a bit better than the first one I think that's because you tried to squish those ellipses a bit too much on that second page but it still looks good so perfect!

Plotted perspective

Your plotted perspective looks great, some of those back edges are even vertical so that's a really good sign!

Rough perspective

On one hand you make a really good job of keeping those boxes in one point and making the vanishing point close to what it should be but on the other some of those lines are really wobbly, i'll give it a pass for now but do make sure to use the ghosting method for every single stroke you do freehand

And on some of those lines you went and redrew over them, don't do that, it's fine, we all fuck up a line sometimes and really want to go over it, but don't, it just makes it look worse, and you won't be as likely to remember your mistake.

Rotated boxes

You did a really good job, but some boxes are missing, and that's not cool your boxes rotate really well, maybe even a bit too fast on that bottom right corner which i can imagine is also a part of why you din't complete the set, but even if it's barely visible that box is part of the exercise and it will also make the rotation even more obvious.

So before moving on I will ask you to finish this exercise, 3 boxes are missing on the top left, 3 on the top right, 2 on the bottom left, and one on the bottom right Just keep going at the exercise like you did before since it's looking really good and like you understand the exercise!

Feel free to refresh your memory and go on the exercise page to make sure you remember every step!

Organic perspective

I feel like you've already taken a bit of a perspective course before, those look great! You use a good deal of foreshortening some, shallower one and you varied your boxes sizes well!

Great job overall!

Don't forget to do your 50percent

Don't forget to do a few warmups (3 ideally) before working each time

And if you need this website is pretty great to help you choose the warmup https://mark-gerarts.github.io/draw-a-card/

Hi Tameraaxo,

Im heiwa and I will try my best to critique your work. From my first glance it looks good.

Lines your lines are pretty consistent and they do not have wobble. It Shows that these lines are confident and on top of that good accuracy as well. You also dont have fraying on both ends. This is good work.

Ghosted Lines These lines also seem pretty consistent, only at minor places i can see that you missed the spot but that's okay. This overall very accurate ( not the requirement to pass the exercise ) but confident ( required ) and you have both so good job here.

Ellipses in planes As your lines the planes are also good and ellipses are also drawn such that you have tried to best cover all the four sides. There's no wobble lines as well. Similar work is seen in table of ellipses. Althoough one can make use of gaps remaining to fit in more ellipses, nevertheless that's just me nitpicking. You have also managed to touch the border's of funnel as well. This is good work.

Plotted Perspective You have managed to draw the crux of the exercise i.e keeping the height of the boxes perpendicular and having only two vanishing points. In your rough perspective I see that your guess work on where the vanishing point will lie has missed quite a few time. That is something to try to improve as you practice more because this is perfectly fine. Im sure you are using ghosting method for that and hence im also sure you will improve on this.

Rotated box Apart from one minor correction that you did this is work of art. As homelander once said, 'Its perfect'

Your organic perspective is clean and good, but i would suggest you to have more drastic changes in vanishing points. Your cubes are also aligned in one single direction. Try to rotate this in multiple ways. I will refrain from giving this as a revision because next exercise is full of these. This is overall and amazing work.

Hello! I'll be critiquing your work. To be honest this will probably be a short one, your homework looks great.

LINES

You've got clean and confident lines and great accuracy. All exercises in this category are very well executed. Well done!

ELLIPSES

Ellipses look smooth and have a consistent shape.

The funnels look great. I like the variety in ellipse size and width.

BOXES

Nice perspective on the Rotated and Organic exercises, you're really good at estimating rotations :)

I have nothing more to say except great work!

I'm marking this lesson as complete and you can move on to the 250 Box Challenge.

Hello there! My name is VnCaheo. Congratulations on completing your first lesson, and now I'll deliver my critique.

Lines

For superimposed lines, I see that there are fraying on both sides for the many lines that you made. Therefore, you should spend a bit more time on placing your pen at the correct position before executing your line. To illustrate:

https://drawabox.com/lesson/1/superimposedlines/fraying

There is relatively little wobbling as you make the left-to-right lines so great job. You also varied the length and direction, which is commendable. These lines wobble a lot more, but this exercise is sufficiently executed.

For ghosted lines, many of them have very good confidence. Some may arc a bit, so you shold try to pivot your arm from the opposite side that you often arc towards (for example, if your lines often curve upwards, then you try to curve downward a bit to balance it out). Remind yourself not to try to correct your mistaken lines as well, as there should only be one decisive line. Overall, you have reached level 2 of this exercise, which means your line is confident and straight, only missing the mark a bit.

in ghosted planes, the issue of your line curving is pretty prominent. You should take note of the aforementioned tip to alleviate this issue. The confidence is maintained, though, so that's a great sign.

Ellipses

For ellipses in tables, some circles and ellipses are drawn through multiple times. Keep in mind that twice is preferred, although you can draw through them thrice. You did try to fit them snuggly in the tables, and the lines are smooth. You can try to improve on the accuracy next.

For ellipses in planes, the problem of the ellipses being circled many times persisted. However, You tried to make the ellipses hit the four border of the planes, which is one of the aims of this exercise. Another issue is that some of your planes are missing the two lines, which you fixed later, but keep that in mind.

Funnels: Most ellipses you drew touch the corner of the funnels, and they align with the central minor axis. The aforementioned of drawing through ellipses is lessened (it is still common, however). So you did a great job.

Boxes

You used a ruler for plotted perspectives, and plotted the lines back to the vanishing points correctly. They are also not messy and very nice to look at because you utilised line weight to distinguish between the massive number of lines. You had a bit of trouble drawing the back line, but that's a minor issue. Overall, you did extremely well for this one.

For rough perspective, you ghosted your boxes. and it didn't look like you struggled with the two faces of the boxes (they should be rectangular). You also extended your lines back to the Vanishing point. However, a reminder that you should only ghost and draw one decisive line instead of trying to correct your mistaken lines. It would look much nicer that way. Overall, there were attempts to hit the Vanishing point, which is the main target of the exercise.

Rotated boxes: The most challenging homework of all. You went through all the steps and also tried to draw all the boxes available. The boxes in the very corner are missing lines, though, so you could remind yourself to add these. Another thing is that some of your lines do not converge at the determined Vanishing Point. See here. Overall though, this work is done to satisfaction.

For organic perspective, you ghosted your boxes and also tried to make them converge. Nonetheless, some of your lines diverge instead of converging. You should check if they converge as they move farther from the viewer instead of diverging. Your foreshortening is also very dramatic for some boxes and this can create size inconsistency. Therefore, try to keep your convergence more shallow for this particular exercise.

Hello there! My name is VnCaheo. Congratulations on completing your first lesson, and now I'll deliver my critique.

Lines

For superimposed lines, I see that there are fraying on both sides for the longer lines that you made. The shorter ones didn't have this issue, suggesting that you took little time to place your pen in the correct position for the longer ones. Therefore, you should spend a bit more time on that and be a bit less hasty for the more difficult ones. To illustrate: https://drawabox.com/lesson/1/superimposedlines/fraying

There is wobbling as you try to reach the end as well. Concentrating on the end point without your instinct trying to correct your movement would improve the trajectory.

For ghosted lines, many of them have very good confidence. Some may arc a bit and wobble, though. to stop your lines from arcing, apply the same technique as superimposed line of focusing on the end point, and try to pivot your arm from the opposite side that you often arc to (for example, if your lines often curve upwards, then you try to curve downward a bit to balance it out). Also take more time to ghost your lines, and remember that once you put your pen down, any chance of fixing mistakes has been ruled out. Don't try to correct your line mid-way through, which can both affect your confidence, line quality and accuracy. This also applies after you draw the line as well, so don't redraw a mistaken line that you made! Nevertheless, your lines can qualify as level 2, which means you are confident enough.

In ghosted planes, your line quality improved a lot. They have better trajectory, only overshooting or undershooting a bit. That's a good sign of improvement. Keep up the good work

Ellipses

You did very well for ellipses in tables, as the ellipses are mostly smoothly drawn through twice or thrice. Some circles and ellipses are are drawn through multiple times though so keep in mind that twice is preferred. They also try to fit snuggly with each other and leave no huge gap, with the exception of the circles which caused you a bit of trouble. You can improve on your ability to draw much more even ellipses next.

For ellipses in planes, always remember that you need to draw through your circles twice or thrice like I just mentioned. Don't do it only once or constantly circle one ellipse. You did try to fit your ellipses and make them touch the border. Some don't hit the mark, but it is sufficiently done

Funnels: Most ellipses you drew touch the corner of the corner, and some align with the central minor axis. One problem is that some ellipses leave gap between each other, or overlay onto another, which is something you should not do. Try to fit them snuggly like in previous exercises.

Boxes

You used a ruler for plotted perspectives, and plotted the lines back to the vanishing points correctly. They are also not messy and very nice to look at. Overall, you did extremely well for this one.

For rough perspective, you ghosted your boxes. and it didn't look like you struggled with the two faces of the boxes (they should be rectangular). You also extended your lines back to the Vanishing point. Overall, there were attempts to hit the Vanishing point, which is the main target of the exercise.

Rotated boxes: The most challenging homework of all. You went through all the steps and also tried to draw all the boxes available. The boxes in the very corner were missing lines, though, so you could remind yourself to add these. It's very important to follow the exercise to the absolute. Try to take your time to hatch the gap between boxes as well.

For organic perspective, you ghosted your boxes and also tried to make them converge. One detail I commend is you not making the foreshortening too drastic (something a LOT of people do, including me), which means you understood the assignment. Two things to note, however. Firstly, some of your lines were parallel or don't converge at all as they move away from the viewer. Although less dramatic convergence is recommended, you should determine whether these are parallel or not. Secondly, you should never repeatedly draw many lines for one edge. There should only be one ghosted line. One decisive line, no more, no less.
