Organic arrows :

-Lines are a bit wobbly sometimes. Also, hatching on the arrows is sometime a bit messy, be sure to take your time.

-The Arrows exercise is not perfect, they still feel a bit flat. You did what was asked in the lesson by overlapping the edges and try to apply perspective. So I consider this exercise done but be sure to work on it as a warm-up before drawing sessions to keep getting better at it.

Organic forms with contour lines :

-Good work on the organic forms w/ contour lines. especially on the ellipses one, on the second page however some of those forms are a bit elongated on the ends. It's fine because the majority are good forms with spherical ends

-On the curve one you overshot some of those contour lines, do not rush and take the time to ghost your lines to have confident yet, accurate enough lines.

Texture analysis :

-Very good work on those textures, I suppose the bottom one is the crumpled paper, it looks like it at least, would be useful in the future to give those textures names. But apart from that very good work, I wish my textures were this good.

dissections :

-For the dissection exercise I often feel like the textures don't wrap around the form, and there is also a lot of scratchy scribbly lines that I'm not a fan of. If a texture has a lot of lines elements, like let's say the inside of a tree trunk, really try to think of these lines as cast shadows rather than lines, and take your time to really define these, even if it means doing less.

This exercise is not meant to be easy so it's fine if it's not good, but be sure to try it again in the future to see how you progressed.

Intersections :

-For the geometric form intersections good work, just one note, only do one line when drawing straight edges like on a box for exemples. I can see some of those edges have two lines. It's just a small thing, other than that you did a good job.

-organic intersections : Good work on those shadows, again, some of those shapes are elongated. Really try to keep them simple.
