Hello Azzunoka, 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. 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, 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.

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.

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 there are also some unnatural bends present in your leaf structures. 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 we 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 keep the line thickness between your phases of construction roughly consistent, but don't forget to construct your edge detail additively as much as possible, that is, on top of your structure, avoid cutting back into the forms you've already drawn as that will cause us to focus too much on manipulating 2d shapes, rather than the 3d edges they represent.

It's good to see that you're also experimenting with some more complex types of leaf structures, and doing so by following the instructions, which allows you to create a much tighter and more solid looking structure that still feels flexible and energetic.

Branches

Moving on to your branches you're not sticking to the instructions for this exercise as closely as you should. While it's good to see that you're usually drawing your edges in segments you're not starting your new segment back at the previous ellipse point and superimposing it on top of the preexisting mark, you're starting your new segments close to where your previous mark ended, 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 don't forget to always draw through them twice, drawing through them only once will cause them to be too loose and unconfident. It's good to see that you're aware of the ellipse degree shift and making use of it in your constructions, which helps these structures feel more solid and believably tridimensional.

Plant Construction Section

And lastly let's take a look at your plant constructions, which are generally coming along well made, as you're following the construction methods and techniques introduced in the lesson which allows you to construct really solid looking and believably tridimensional structures. I can see a good developing sense of spatial reasoning in these pages.

However there are some issues present in these pages which are holding you back from your full potential. So here are the points you should keep in mind whenever you tackle these exercises again so that you can continue to develop your skills.

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 leaves 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. Not drawing through 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.

Another issue present in your structures is that when you put contour lines on your forms they don't really communicate any new information. Those kinds of contour lines, the ones that sit on the surface of a single form, only serve to take a form that can already be interpreted as 3 dimensional, and clarify it, while they're useful for introducing the concept of a contour line in practice it can be really hard to apply them incorrectly, if even 1 of your lines isn't in sync with the others the solidity of your structure will suffer. As such it's best to focus only on contours that communicate intersections.

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

And lastly let's take a look at your textures, they're generally moving in the right direction but they still need some work, as it's looking very explicit as you often attempt to capture texture with big areas of black which often cover a major part of your construction. You don't always design your shadows with a specific purpose in mind.

So let's revisit how texture in Drawabox is approached, by looking back on this page we can refresh our memory on texture through the lens of Drawabox and see that it is not used to make our work aesthetic or good looking, instead every textural form we draw is based on what's physically present in our reference.

Our focus should be on understanding how each individual form sits in 3D space and how that form then creates a shadow that is cast onto that same surface. Only after analyzing all of this information present in our reference will we be able to translate it to our construction. This means that the shape of our shadow is important as it's the shape that defines the relationships between the form casting it and the surface it's being cast on, which is why we need to consider carefully how to design a shadow shape that feels dynamic and communicates this tridimensional information.

This approach is of course much harder than basing our understanding of texture on other methods that may seem more intuitive or basing it on the idea that texture = making our work look good, but in the long run this method of applying texture is the one that enforces the ideals of spatial reasoning taught in this course. By following these ideals, you'll find yourself asking how to convey texture in the most efficient way possible, with less lines and ink, focusing on the implicit mark-making techniques introduced in Lesson 2. Make sure to go over these reminders in order to solidify your understanding of texture further.

Final Thoughts

In general your work is looking really good, you're starting to understand the purpose of these techniques and exercises and making use of them in your work effectively, as such you demonstrate that your sense of spatial reasoning is developing really nicely. Just don't forget to always follow the instructions as closely as possible.

I'm going to be marking this lesson as complete. Good luck in Lesson 4.
