Hello there! Congrats for getting through this lesson and the 250 Box Challenge before that. Here are my observations:

Organic Arrows:

Your lines are a bit wobbly and erratic still, especially the bits of added line weight on top, which look self-conscious and slow instead of confident and ghosted. I could be wrong, but it bears repeating that the lines for adding line weight should be ghosted and drawn from the shoulder as well. Also, in one example in particular you avoided overlapping your lines which made the result look rather flat.

Organic Forms with Contour Lines :

Other than than the lack of confidence in your lines, it looks like you're struggling a bit with the overall forms. These should have consistent width and each end should be as round as a circle (basically, two identical balls connected by a tube). Yours tend to taper from one end or pinch at the middle. Other than that your ellipses and curves aren't aligned with the center line and they often miss the boundaries but that's mostly due to the overall form being flawed from the start.

Texture Analysis :

I don't have many complaints about this exercise; you managed to make smooth, seamless transitions with your gradients although with some marks it looks as if you're chicken-scratching or adding short strokes that don't serve a purpose. Also, avoid using lines to express your shadows in the lighter are and use shapes instead: https://i.imgur.com/M9JJfr4.png. This will help you make each stroke you make more purposeful instead of random.

Dissections:

Other than the aforementioned issues in your organic forms, here are a few things I saw here: first it looks like you're especially rushing here. A lot of your lines look more like scribbles than thought-out lines with purpose since they don't construct a shape or wrap around the forms. For a lot of these (the corral and mushroom ones for example) you seem to be drawing the contours of each small shape instead of the shadows they're casting over the form, which is what this exercise is about, and when you're drawing shadows, these look more like simple lines with thick line weight instead of shapes cast by the silhouette of the form. And, again, the textures should be wrapping around the form: https://d15v304a6xpq4b.cloudfront.net/lesson_images/e58b7887.jpg. Lastly, you only drew 3 forms in each page, where Uncomfortable's examples show about 7 forms and 15 to 20 textures on each page instead.

I really recommend you try taking your time with each every exercise as rushing will keep you from fulfilling what the course is about, and that is drawing shapes that are solid and look like they belong in 3D space.

Form Intersections:

These look mostly good (again, some of your lines have a wobble to them and some of your boxes are pretty janky) though one thing of note is that your cylinders have inconsistent foreshortening with the other shapes, which are a lot shallower in their foreshortening. Consistent foreshortening helps sell the illusion that all these forms occupy the same space.

Organic Intersections:

Your issues with organic forms crop up again, moreover, some of the forms on top look like they're floating instead of slumping over the forms beneath. Other than that your shadows aren't convincing as they don't wrap around the form they're cast on and don't express its shape, with one example of a shadow cast in the wrong direction: https://i.imgur.com/qePQvBE.png

Bottom line, I think you should try to take your time when going through these exercises and rewatch Uncomfortable's demos to try to fulfill what you're asked to do in each one. It's only normal to not nail any of these lessons in the first go and I advise you to go back to some of these exercises before continuing to Lesson 3.

Great, this is looking much better. I'll go ahead and mark this homework as complete.

Do keep in mind to take as much time as you need with the next assignments, and good luck.
