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

Arrows

Starting with your arrows you're drawing your marks with a good deal of confidence which helps solidify the feeling of fluidity that arrows posses as they move through all three dimensions of the world they exist in. However your arrows have little to no foreshortening, make sure to explore the size difference between arrow segments more in order to make better use of the depth of the page and push your understanding of tridimensional space further.

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, in this case your marks must go from one end of your arrow's end, to the other, running perpendicular to the length of the arrow, and your marks must 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.

In general you're moving in the right direction, so keep tackling this exercise during your warm ups in order take your understanding of arrows and 3D space further, experiment with the different ways arrows can twist and bend and move across space, try different rates of foreshortening and experiment with the size difference between different segments, the negative space between overlaps, all of these will help you challenge yourself and develop your skills further.

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.

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 following the instructions for the exercise, you're drawing your edges in segments which allows you to maintain higher control over your marks which allows you to create some solid but still organic looking structures.

There are some 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 nicely. 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 focusing 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 issues in your work that hold you back from your full potential, so here are the points you should address the next time you tackle these exercises.

Make sure that you're always drawing through your forms and constructing them fully, I've noticed that in some of your constructions, such as in here and here you don't construct the part of your structure which would be invisible to the viewer, 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 you're relying on your observation skills and trying to copy your reference, instead of engaging your sense of spatial reasoning and truly trying to understand how the object you're drawing works, how each and every forms exists in 3d space relative to one another.

Keep the stages of construction between your forms tight and specific, don't leave gaps in between a leaf's flow line and it's outer edges such as in here, they must connect.

• It's good to see that you're drawing your plant pots around a minor axis as that helps you keep your several ellipses aligned to each other more easily, it's also good that you construct the outer rim that's present in most types of plant pots, and add a ground plane to your constructions, just don't forget to always add it in. In general all of these points help you construct a much more solid and believable tridimensional structure.

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.

The leaf structures in here are looser than they could be, because you did not put down a boundary, you didn't establish the form 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 will be much more solid and specific.

The figs in this construction are also flatter than they should be because you end up skipping steps and drawing their outlines, rather than constructing the protuding part of the structure as a tridimensional form, you actually follow this concept much better in this pomegranate construction where you fully construct the extra part of the structure as a new form, which reinforces the illusion of tridimensionality in it.

Don't forget to make use of edge detail in your plant constructions.

Final Thoughts

In general you are doing really well with these exercises, you're demonstrating a developing sense of spatial reasoning in these pages. While there are some issues which hold you back from your full potential I believe these issues can be addressed during your warm ups and that you are ready for the next lesson. I'm going to be marking this submission as complete, good luck in Lesson 4.
