Hello Michelanjello, I'm ThatOneMushroomGuy and I'll be the TA handling your critique today.

Arrows

Starting with your arrows your lines are looking fairly confident and smooth, which helps communicate a nice sense of fluidity in your arrows as they move through the world. You're keeping foreshortening in mind while constructing your arrows which allows you to make really good use of perspective and the depth of your page, this gives a nice extra layer of tridimensionality to your arrows.

Your usage of hatching helps you establish how your arrows twist and turn in space and further your own understanding of the tridimensional space these objects occupy, but do remember that your hatching lines must still follow the principles of ghosting and mark-making, they must have clear end and start points, be carefully planned and executed and not end at arbitrary points. As a finishing touch to your arrows don't forget to make use of added line weight on top of the overlaps to reinforce their depth.

Still speaking of hatching, there are a couple of times where you've placed it incorrectly, making it seem like your arrow is getting bigger the further away it is, and getting smaller as it gets closer to the viewer, which goes against the rules of perspective.

• Perspective works in the following manner: things that are further away from the viewer will look smaller, and as they get closer to the viewer they'll look bigger. The way this affects an object of consistent size and width that stretches across space is that certain segments of this object will look bigger and others smaller, either gradually or dramatically depending on the perspective of the scene, as such the bigger part of the arrow will always be the one that's closest to the viewer so the segment that's behind it should be the one receiving the hatching.

You've done a good job on this exercise, what I'd like to tell you so that can keep getting the most out of this exercise is actually to encourage you to get out of your comfort zone more often the next time you tackle this exercise, try arrows with different kinds of twists and turns and different rates of foreshortening, keep in mind that arrows are very flexible objects and can move freely across the world in all sorts of manners, so you should push yourself and explore the different possibilities.

Leaves

The linework for your leaves is looking smooth which helps communicate their fluidity and sense of energy, it's good that you're not only trying to capture how these structures sit statically within space, but also how they move across it from moment to moment, however you also have some unnatural bends present in your leaves. Keep in mind that even though leaves are very flexible structures, that mostly applies to their length and not their width. They're like a piece of paper, not a piece of rubber, they can fold and bend in a lot of ways, but they can't stretch or compress, and if you try to force them to they'll simply rip apart.

Your addition of edge detail is generally looking good, as you don't usually attempt to capture more than one piece of edge detail at a time, and you generally construct your edge detail additively. You're also keeping the line thickness between your phases of construction roughly consistent, all of which is very good and helps you create a tighter, more solid construction that still feels fluid and energetic.

It's good to see that you've experimented with complex leaf structures but remember not to skip construction steps when approaching these more intricate structures.

This leaf construction is looser than it could be, because you did not put establish the boundary that all of the later structures should abide to, despite complex structures being made up of several different parts, they still exist as a single entity, by not skipping construction steps you can ensure that your constructions are much more solid and specific.

Your addition of texture is coming along quite explicitly made as you outline your textures which leaves no transitions from light to dark in an attempt to capture the representation of what's going on with your structure.

This doesn't allow you to properly focus on the cast shadows present and thus your addition of texture is less specific than it could be. There's much more going on than just a few stray marks implying veins and we can do much more to accurately communicate this type of texture, take a look at this informal demo on how to approach leaf texture, and make sure to give these reminders on how texture works in Drawabox a read.

Branches

Moving on to your branches they are coming along really decently made as you're generally following the instructions for the exercise, but they can still be improved. While it's good to see that you're drawing your edges in segments you're not always extending said segment completely up to the halfway point between ellipses, which partially removes the healthy overlaps we seek to achieve in these structures.

So remember how branches should be approached, by having your segment start at the first ellipse point, extending it past the second ellipse and fully up to the halfway point to the third ellipse, afterwards you'll start a new segment, making sure to place your pen at the second ellipse and repeat this pattern until your entire branch is complete.

For ellipses it's good to see that you're making an attempt to always draw through them twice, as that allows for a smoother mark overall. When it comes to your application of the ellipse degree shift to your branches it can be improved, as it stands your degrees are too consistent and hardly change which is a mistake that flattens your structures. Remember that as a form shifts in relation to the viewer, so will the degree of the ellipses within that structure also shift.

Plant Construction Section

And lastly let's take a look at your plant constructions, which are coming along quite nicely made. You're generally making use of the construction methods and techniques introduced in this Lesson which helps you create the illusion of tridimensionality in your work, you're not only trying to capture what these structures look like, but you also focus on how they work, how they exist fully in tridimensional space by drawing through your forms and thinking about the way each piece of your construction exists in relation to one another.

This is all very good and it's helping you develop a strong sense of spatial reasoning, there are only a couple of small things that if kept in mind will help you take your work to the next level.

Always keep in mind that the construction methods and techniques introduced in this course must always be applied to your work, as they're tools which will help you construct much tighter and solid looking structures, while this is something that you generally respect, for this construction and this flower you are skipping construction steps which has caused your constructions to look flatter and less tridimensional than they could otherwise be. For example in here you have drawn the petals that are further away from the viewer as their outline only, instead of constructing each of them with the leaf construction method and then connecting them together. Remember that these are not guidelines or suggestions - they are rules.

Make sure that you're always drawing through your forms and constructing them fully, I've noticed that in some of your constructions you don't draw through some of your forms, such as petals or branch like structures, this limits your ability to work through these tridimensional puzzles and limits how much you're getting out of the exercise as not drawing throug your forms means relying on your observation skills, instead of engaging your sense of spatial reasoning and truly trying to understand how the object you're drawing works, where it comes from, what it attaches to.

When approaching cylindrical structures such as plant pots and mushrooms starting with a minor axis will help you keep your several ellises aligned to each other more easily.

Final Thoughts

In general you are doing well, I believe that in these pages you have demonstrated that you do understand the way these construction methods and techniques should be used and why they're important for your work even if it can be improved upon, as such I'm going to be marking this submission as complete. Good luck in Lesson 4.
