Hello zularka, 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. 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.

You've done a good job here, so keep experimenting with the different kinds of twists and turns and different rates of foreshortening that are possible for arrows, remember that these are very flexible objects that can move freely across the world in all sorts of ways, so you should push yourself and explore the different possibilities in order to keep honing your skills.

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.

Another thing to note is that the majority of your leaf structures don't fold or bend in any way, this is something to keep an eye on whenever you tackle this exercise again, as leaves are organic structures that are affected by all sorts of forces, you'll improve much more by thinking about the way these objects look when they move through the world from moment to moment, instead of just trying to capture how they sit statically within it.

You're not making use of edge detail in your pages, edge detail would have greatly helped you further communicate the form of your structures and how they move through space, but by not adding it they're left very simple, so make sure to add edge detail whenever possible, and remember that only the last step of leaf construction - texture - is optional.

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, sometimes you're drawing your outer edges past the halfway point between ellipses, which partially removes the healthy overlaps we seek to achieve in these structures as it causes you to lose some control over your marks.

There are a lot of visible tails present in these branch structures, while this is a very common mistake we can attempt to mitigate it by limiting the amount of ellipses in our branches, by spacing them further apart we'll allow for a bigger length of runway between ellipses, and ensure a smoother, more seamless transition between marks.

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. 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.

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. This is something that you do generally understand, but in some small details you forgot to fully construct your work, such as for the small leave like structures in this construction and this daffodil construction. They're not guidelines or suggestions - they are rules.

Speaking of it, you're taking a great first step towards starting to think of how to break down different structures in this construction but it does end up accidentally stiffening the flower structure a bit if you don't approach it with the leaf construction method which naturally adds a sense of flow and energy to your work.

One way in which we can approach this structure that ensures the petal structures are still flowing nicely and that all of the relationships between the different forms are tight and specific is by using a slightly tapered cylinder in order to construct the main body of the leaf shape, then afterwards make use of the leaf construction method, build it on top of the cylinder in order to capture the flow of the different sections of the leaf structure, and lastly connect them together, making use of edge detail in order to finish the complex structure. I actually put together a quick demonstration of how this would look like un the context of a Daffodil for a different student once, and I believe you will find it helpful.

It's really good to see that you're making use of elliptical boundaries in order to construct some of your flowers, this allows you to keep the distance and size of the petals consistent with onr another and helps reinforce the illusion of tridimensionality in your work.

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.

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