Hello Tancoque, 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 good that you're making use of added line weight on top of the overlaps in order to reinforce their depth.

In general you're doing well in this exercise, your arrows are looking fluid and tridimensional and there's a good variety in the rates of foreshortening and the way they twist and bend through space, so don't forget to keep tackling this exercise during your warm ups in order take your understanding of arrows and 3D space even 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 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.

It's good to see that you're also experimenting with some more complex types of leaf structures, and doing so by following the instructions, which allows you to create a much tighter and more solid looking structure that still feels flexible and energetic.

Branches

Moving on to your branches they are coming along really decently made as you're generally following the instructions for the exercise, but they can still be improved. 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 often 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 don't forget how branches should be approached, your segments must start at your ellipse points, you must extend your mark past the next ellipse, and stop at the halfway point between that ellipse and the next, with the new segment repeating the pattern until your branch is complete. This helps us maintain control of our marks and allows for a healthy overlap between them.

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 coming along nicely, you're sticking to the construction methods and techniques introduced in this Lesson which helps you create some very tridimensional and solid looking constructions.

You're not only trying to capture what these structures look like, but you're focusing on how they work, how they exist fully in their tridimensional space. This is all very good and it's helping you develop a strong sense of spatial reasoning, there are only two main issues that should be addressed as they hold your work back from being the best it could be.

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.

You're not always 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.

Another thing to keep in mind that's present in your structures is that when you put contour lines on your forms they don't always communicate any new information. Those kinds of contour lines, the ones that sit on the surface of a single form, only serve to take a form that can already be interpreted as 3 dimensional, and clarify it, while they're useful for introducing the concept of a contour line in practice it can be really hard to apply them incorrectly, if even 1 of your lines isn't in sync with the others the solidity of your structure will suffer. As such it's best to focus only on contours that communicate intersections.

Final Thoughts

You're doing really well. For the most part you apply the construction methods and techniques to great effect and you're demonstrating a great understanding of spatial reasoning in your pages. I believe you're ready for the challenges present in the next lesson, as such I'll be marking this submission as complete. Good luck in Lesson 4.
