Hello mikeead83, 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, it's also good that you're making use of added line weight in order to reinforce the depth of your arrows, but don't forget that it must be added subtly to your work, only once, on top of the overlaps.

In general you're doing well, so keep tackling this exercise during your warm ups in order to 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 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.

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.

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 structure is looser than it could be, because you skipped construction steps and tried to capture the complex form of the structure right away, instead of constructing each individual arm with the leaf construction method and only then connecting them together. Even though leaves are single entities they can still made be made up of several parts.

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 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 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 generally coming along well made. For the most part you're sticking to the construction methods and techniques introduced in the lesson which allows you to construct some really solid looking and believably tridimensional structures, you're demonstrating a strong, developing sense of spatial reasoning in these pages.

But there are a couple of things that can be improved in your work, so here are the points you should keep in mind whenever you tackle these exercises again, so that you can continue to improve your skills.

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, there are times where you deviate from the construction methods by not starting your branches with a minor axis or keeping your leaf structures simple. Remember that they're not guidelines or suggestions - they are rules.

Make sure to keep all stages of your construction tight and specific, don't leave gaps in between stages of construction, such as a leaf's flow of line and it's outer edges, they must connect.

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.

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