Thank you very much for all the feedback! Hopefully I'll be able to improve my constructional techniques soon.

Thank you very much for the feedback. I've drawn along to the lobster demo and done two more constructions, as you asked. Hopefully I didn't misinterpret any of your advice.

You have a very good showing here. Lines and strokes are confident, the textures are clean, and the solid forms feel solid. To get more specific...

-Arrows

The perspective here is handled well. Arrows get bigger as they get closer, and the spacing of the curvature gets smaller as it gets further away. The only remote issue I see is that some of the hatching lines go a little outside of the arrows they are drawn on, but this is not a consistent issue.

-Organic forms with contours

Your organic forms are solid, but there's still room for improvement. On some of them, the degrees of the curves don't seem to shift very much, if at all. It's important to get this for conveying the fact that this form is present in a 3D space with 3D perspective. You should be able to get this with practice. In terms of smaller things, some curves either don't reach the edge of their respective forms or go past the edge on occasion.

One final thing: While you actually handle it pretty well here, don't be too eager to make sausage forms where the ends are different sizes. It's best to keep them simple for practice's sake. You do a good job portraying it as exaggerated perspective, but still, simpler is better. Just keep this in mind.

Aside from these things, your organic forms are quite good. You seem to be drawing them with confidence and have done a good job with elements like keeping the ellipses' minor axes aligned to the spines and making sure your contours adhere to the forms.

-Texture analysis

You've done a great job with analyzing these textures. You seem to be focusing on drawing shadow shapes and making purposeful strokes with your pen, whilst analyzing your references carefully. The gradient section features very smooth transition from dark to light throughout, which is impressive and respectable.

Now, that being said, there is a weak point here. On the feathers texture, you did initially seem to focus more on using lines to portray some of the texture on individual feathers. You strayed away from this on the gradient section, but still, do try to stay away from doing this. Even for the smallest shadows where a line may seem appropriate, try to make it a shape of some sort. Still, you did a great job here overall.

-Dissections

The same strengths displayed in the analysis section are displayed here. You've analyzed your references carefully and done a solid job with focusing on shadow shapes. There are some instances where you use lines, and the same criticism for before applies here as well.

Another thing that you did well is applying the textures to the forms. They break silhouette in most cases, and they clearly follow the curvature. The one exception that jumps out to me is the waffle texture on the second page. It looks flat on the section it was applied to and doesn't really look right. Aside from that one texture, everything here is quite good.

-Form Intersections

Your forms all feel like they occupy the same space, which is the main goal here. The perspective on all of them feels consistent for the most part. Your intersections are quite good as well. You've done a good job of making sure that they adhere to both shapes involved in said intersection. My main issue here is that you could have used some more lineweight to add clarity. Amidst all the forms joining together, it can be hard to tell what exactly is happening. You've applied a little to the intersections themselves, and the hatching certainly helps. I still think a bit more line weight in some places, like on the "visible" lines of the boxes or some heavier weight on the intersections, would help.

-Organic Intersections

This part is done very well. All the shadows stick to the forms they're cast onto fairly well, and the forms all feel like they are properly resting along one another. You've also done a good job keeping the forms relatively simple here. The main issues are just a couple of relatively small ones: the top form on the second page has contours that don't convincingly shift degrees, and shadows of the forms on the "floor" of the first one don't merge together as much as I would have expected. Also, again, I think some more use of line weight for clarity would be good. Using it on edges of some forms to distinguish which organic forms are in front of which is helpful for this.

I must say, you have quite a good showing here. I want to give in depth feedback, but you have a very good understanding of each exercise and make very few, if any mistakes.

Your strokes are confident for the most part, your ellipses in your organic forms change degrees in ways that create a sense of depth and form, your intersecting forms feel like they occupy the same space, your textures adhere to their respective surfaces, etc. The only thing that I think I can count as a mistake is that some of your organic forms in your organic intersections stray away from the simple two-balls-connected-by-a-cylinder structure that's recommended, but you drew more than enough of them that they aren't much of an issue.

I'm also not sure what to say about the colored inks for some of your pages, particularly the pink ink for the form intersections. I personally don't count it as an issue, but some others might. Just for future reference, I recommend keeping the ink color to black.

There is room for improvement, but I think you're off to a solid start so far. Here's what stood out to me:

I notice some wobble in your lines, especially in the earlier pages. This is something that you'll improve as you develop line confidence. Keep on ghosting your lines, and you'll be good on this front. I also notice you overshoot or undershoot your target occasionally. Again, this should improve with practice.

In any case, you should also experiment with the speed at which you make your lines. You may stray from the target point or draw before or past it, depending on if you make your stroke too slowly or too quickly.

I don't have much to say about the ellipses. You draw through them twice and appear to be aiming for them to be bound within their respective regions, which is good. You also appear to draw them with at least some confidence, which is also good. The main issue, the accuracy of your ellipses, should improve as you practice them.

Your boxes are fairly solid so far. By this point, your line confidence has shown some respectable improvement. The flaws in perspective aren't too much of an issue right now; you will be able to improve this as you continue to draw more boxes.

You are welcome; I wish you the best of luck going forward.

You've done a pretty good job with lesson 2 overall. I just have a few issues to point out.

On the organic forms, you seem to focus a lot on adding a good number of ellipses/contours. While having a good number of them is important to a point, I think it's excessive here. I'd personally recommend sticking to 4-5 for the average form - maybe 6 if it's a particularly large form. The main issue here, however, is the degrees of the ellipses & curves. The degrees on them don't really change all that much. It's important to incorporate those changes in degrees to help portray the shift in perspective.

Your arrows are pretty solid overall. On a couple of them, the gaps in the folds don't get larger as they get closer, but you avoid this issue in most of your arrows.

The texture exercises are quite good. You've done a solid job with observing your references carefully and applying what you see to your drawings. You also do a good job with making the textures adhere to their surfaces on the dissections exercise. My only point for critique is that the gradients for the first two textures come to a somewhat abrupt stop instead of smoothly transitioning into white space. You did a very good job with this on the third one, however.

The form intersections and organic intersections are quite good. The forms all feel like they occupy the same space together, complete with consistent foreshortening. My only point of critique is that on the last page of organic intersections, you drew three smaller piles instead of one big one. I'm not certain that this is wrong persay, but it is good to draw bigger when you can. Keep this in mind for the future.

Also, I don't wish to be snarky, but do be sure that the photos are not upside down, next time. Drawings are a fair bit harder to fully critique when they're not right-side-up.

You have a pretty solid showing here, with just a few issues to point out.

The arrows are pretty good, getting bigger as they get closer to the viewer. There are some here and there where the gaps in the folds don't increase in size as they get closer, but this isn't an entirely consistent occurrence.

Your branches are quite good. They appear solid and well constructed, with barely any visible fraying tails off the sides in sight. My only point of critique here is that the degrees of the ellipses don't seem to change all that much in some of your branches. There are other branches in here where you do apply this, however.

Your leaves are very good, being drawn with confidence and control. You do seem to use subtractive construction somewhat often, however, which is a big no-no. You should try to keep it largely to additive construction.

I don't have much in the way of criticism for the actual plant constructions, outside of criticisms already brought up for the leaves and branches. You're clearly breaking these plants down to simpler shapes and working from there, and you seem to be working with a great sense of care. You clearly put a lot of work into the observation side of things, which is good. My only criticism here is that, on the last drawing, you don't seem to use line weight much to add clarity to the piece and don't seem to mark out the intersections between forms. Both of these will be quite important going forward, so try to incorporate these practices in your drawings more as you go forward.

You actually did a great job for the most part, especially with the later portions. I admittedly do notice that you seem to have some issues with line confidence.

The arrows are where I think you have the most issues. I notice that some of your arrows don't get smaller as they get further away, and the gaps between folds don't get smaller either. This isn't the case with all the arrows you made, but it is a case with a number of them.

The main issue I see in your organic forms is the degrees of your ellipses. On that first page, there is very little variation in the degrees of the ellipses as you go from one side of each form to the other. You do take steps toward improving this with the contour curves, however, which is good.

Your texture work is very solid. I don't see any instances of scribbling, stippling, or anything of that sort; every stroke appears to be deliberate, which is good. My only possible point for criticism would be that I notice you only break silhouette a bit in the organic forms dissections pages. In a number of cases, the silhouette isn't really broken at all. It seems this may be partially a result of the textures you picked. In any case, you do still break silhouette in a number of cases where you can, and the textures properly adhere to the surface, so I don't have a lot to critique here.

Your intersecting forms and organic intersections are all very good. None of the shapes feel like they don't belong in the same space as the others. Your actual intersections are handled well, too. My only critique is that you didn't apply a drop shadow for organic intersections, but this isn't really a major issue; it's just a nice thing to do.

You are welcome!
