For the arrows exercise, the flow and shape of your arrows are good. Some of the shading seems to be misplaced, with some of the shadows being in front of the fold or extending out farther than you might expect. The shadows need to go inside each of the folds. Adding line weight to solidify the overlap will help make your arrow drawings clearer as well. Here's a link to the step on the lesson page.

For the organic form with contours portion, focus on keeping your forms simple. Here's a list of things to avoid as well as an image showing examples. Many of the forms you've drawn are pinched, elongated, and have ends of different sizes. Consider refining the base shapes of these forms as you engage with this exercise in the future.

I'm inexperienced when it comes to textures, so I won't comment on that section. Same for the form intersections exercise, since I'm less experience in basic shape construction as well.

I do want to make a point on your markmaking. Some of your lines lack confidence, and are curved or wobbly. I noticed this in the center lines you drew for the organic forms excercise, as well as in some of the lines drawn in your form intersections exercise. The center lines of your organic forms are wobbly, and sometimes miss going through the center of the forms. Takes some time to ghost and plan those lines as well, I was pretty quick with my center lines when I first did the exercise too. You might benefit from reviewing this portion of lesson 1. Consider the confidence you have in you markmaking when you practice ghosting lines and such during warmups.

Your organic intersection drawings are good. The overlapping and shadows are believable. Some of the forms you've made are elongated and more complicated like in the organic forms section earlier. Here's the details on this from the assignment page.

That's everything I noticed. The work you submitted was good, so just keep some of these points in mind as you practice these exercises as warmups in the future. Move on to lesson 3 when you're ready.

Thanks for reading, and good luck!
