Hello Mikool, 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.

Generally you're doing a good job with this exercise, I'd like to encourage you to get out of your comfort zone more often the next time you tackle this exercise in order to keep pushing yourself. 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.

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 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 need to make use of edge detail more thoroughly in your leaf structures as it's an essential step to communicating how your structure sits in space, but it 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.

Branches

Moving on to your branches they are coming along really decently made as you're following the instructions for the exercise, you're drawing your edges in segments which allows you to maintain higher control over your marks and helps you create solid but still organic looking structures.

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 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, for this bonsai tree construction you deviate from the construction methods by not starting your branches with a minor axis. Remember what these are not guidelines or suggestions - they are rules.

Make sure to fully construct each form present in your construction, don't leave anything open ended such as these vases. Speaking of plant pots when approaching cylindrical structures make sure to start with a minor axis in order to keep your several ellipses aligned to each other more easily. Going further don't forget to construct the outer rim that's present in most types of plant pots, and make sure to add a ground plane to your structures, this line is necessary when constructing plant pots because otherwise your structure will look like it's floating in mind air, which breaks the illusion of the construction.

At points you're drawing through your ellipses way too many times which causes them to look too loose and messy. Try to draw through your ellipses two times only, three times is also accepted.

When constructing forking knots and branches don't forget to use the method outlined here in order to ensure your structure will be specific and more tridimensional.

And lastly let's take a look at your addition of texture to these structures, which needs some work as it's looking very explicit because you don't design your shadows with a specific purpose in mind and so there are not a lot of clear focal points of detail in your constructions.

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 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.
