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

First things first, I have noticed that in your first three pages you have taped additional arrows, branches and leaves to your pages. This leads me to believe that the reason you've done so was to hide and replace unfavorable instances of the exercise, keep in mind that this counts as grinding and doing more than the quantity that was assigned in the homework section.

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 the three dimensions of the world they exist in. You're keeping foreshorting in mind while constructing your arrows which allows you to make good use of 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 good that you're making use of added line weight on top of the overlaps in order to reinforce their depth, but remember that this lineweight must be added subtly, with a single mark being superimposed on top of your lines.

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.

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 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 it's good that you are starting to understand the instructions for the exercise, but there are still a couple of places where you're deviating from the instructions, for example in here while it's good to see that you're drawing your edges in segments when you start a new segment you do so around the place your last mark ended, instead of back at the previous ellipse point which essentially removes the healthy overlaps we're trying to achieve with this exercise.

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 nicely. You're usually make use of the construction methods and techniques introduced in this lesson which helps you create the illusion of tridimensionality in your work, you're starting to develop a strong sense of spatial reasoning.

This is all very good and it's helping you develop a strong sense of spatial reasoning, but here are some more things you should keep in mind when tackling these exercises again in order to take your work into the next level.

There are a couple of times where you've deviated from the instructions for the exercise, for example in this construction where the forms you've constructed are vague and do not communicate any sense of form or tridimensionality, it seems to me that they're some kind of leaf structure and as such they should have been drawn with the leaf construction method.

And for this construction you have not drawn the smallest branches by starting with a minor axis.

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. They're not guidelines or suggestions - they are rules.

I have noticed some very faint lines when you tried to draw boundaries when constructing these flower structures, but their faintness and grey color makes me think this might have been drawn in pencil. If this is the case, remembertl that the fineliner is a required tool when going through this course on the official path and using pencil is wrong and will not be accepted in the future.

If this was not the case, just keep in mind that your boundaries should be drawn with the same general line thickness as the rest of the construction.

Final Thoughts

In general your work is moving in the right direction, you're usually following the instructions to the exercises and your work is starting to look tridimensional do to that.

I believe you're ready to tackle the spatial reasoning challenges found in the next lesson, as such I'm going to be marking this submission as complete. Good luck in Lesson 4.
