Hello Chy, 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.

It's good that you're making use of added line weight on top of the overlaps in order to reinforce their depth, but ease up a bit on your lineweight, it's thick, with several passes going over the same marks.

Instead, lineweight must be subtle, used only to clarify the overlaps between the forms that are being built up, as explained here.

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.

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.

Branches

Moving on to your branches you are deviating from the instructions for this exercise because you're not following the instructions for how to draw the edges as shown in the exercise instructions. While it's good to see that you're drawing your your edges in segments, you're not extending said segments completely up to the halfway point between ellipses, which 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.

You should also limit 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. 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.

Make sure that you're always drawing through your forms and constructing them fully, I've noticed that in some of your constructions you don't draw through some of your forms, such as petals, 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 relying on your observation skills, instead of engaging your sense of spatial reasoning and truly trying to understand how the object you're drawing works, where it comes from, what it attaches to.

You're taking a great first step towards starting to think of how to break down different structures in this red angel's trumpet, but it does end up accidentally stiffening the inner structure a bit if you don't approach it with the leaf construction method which naturally adds a sense of flow and energy to your work.

One way in which we can approach this structure that ensures the petal structures are still flowing nicely and that all of the relationships between the different forms are tight and specific is by using a slightly tapered cylinder in order to construct the main body of the leaf shape, then afterwards make use of the leaf construction method, build it on top of the cylinder in order to capture the flow of the different sections of the leaf structure, and lastly connect them together, making use of edge detail in order to finish the complex structure. I actually put together a quick demonstration of how this would look like in the context of a Daffodil for a different student once, and I believe you will find it helpful.

• Because we're drawing on a flat piece of paper, we have a lot of freedom to make whatever marks we choose - it just so happens that the majority of those marks will contradict the illusion you're trying to create and remind the viewer that they're just looking at a series of lines on a flat piece of paper. In order to avoid this and stick only to the marks that reinforce the illusion we're creating, we can force ourselves to adhere to certain rules as we build up our constructions.

• For example - once you've put a form down on the page, do not attempt to alter its silhouette. Its silhouette is just a shape on the page which represents the form we're drawing, but its connection to that form is entirely based on its current shape. If you change that shape, you won't alter the form it represents - you'll just break the connection, leaving yourself with a flat shape. We can see this most easily in this example of what happens when we cut back into the silhouette of a form.

While this is something that you do generally respect, we can see moments where you've cut back into your silhouettes, such as in here and in here, which flattens the structure.

You can find here more information that talks about how to make use of organic forms to construct plants that aren't simple branches with leaf structures attached to them, and you can see here how you can construct on top of your preexisting structures with new organic forms.

Final Thoughts

In general your work is looking really good, you're starting to understand the purpose of these techniques and exercises and making use of them in your work effectively, as such you demonstrate that your sense of spatial reasoning is developing really nicely.

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