Hello pandrawamonium, 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 foreshorting 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 good extra layer of tridimensionality to your arrows, but do not be afraid of letting edges overlap as they create a more solid structure. In order to achieve a more cohesive arrow construction use the ghosting method, that way can gauge whether your lines would look right and overlap the way they should before committing to any marks.

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.

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 edge detail is looking quite well made, you're not attempting to capture more than one piece of edge detail at a time, and you're often approaching it additively - that is, constructing it on top of your preexisting structure, as well as putting it down with the same general line thickness as the rest of your construction, all of these are good things that help you construct solid and tight structures that still feel 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.

Don't forget to always draw through your ellipses twice as this will create a smoother and more confident look in your marks. 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, 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.

I've noticed that for these pages you had a tendency to choose very similar plant structures for the majority of your pages, while this is not necessarily a mistake it can end up limiting your ability to hone your skills and fully become acquaintanced with the construction techniques and methods, choosing some less leafy and other types of structures would have allowed you to focus more on applying the different construction techniques and methods to your structures, rather than utilizing the exact same construction methods for the exact same challenge (flower-like structures).

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. Remember that they're not guidelines or suggestions - they are rules.

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.

When it comes to your addition of edge detail you need to spend more time with the execution of each mark - because there are so many and they seem individually unimportant, you're putting less time into each one and so they do not properly rise off and return to the existing stroke - there are often gaps, overshoots, and zigzagging marks which is a mistake that could be avoided by putting more time into the work. No mark you draw is unimportant - if you decided it was worth adding, it's worth giving as much time as it needs to be done to the best of your current ability.

Final Thoughts

In general your work is starting to move in the right direction, you're starting to understand the purpose of these techniques and exercises and developing your sense of spatial reasoning.

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