Helloo Drewanowl!

First of all congrats on finishing all the exercises! This is quite a tough lesson.

So i'll point out some stuff here.

Arrows

You did a great job compressing the arrows so they look bigger as they get closer to the viewer, also they have a nice flow. However i noticed some issues with your lines, there's a bit of scribbling on some parts, so remember that if you'd like to add lineweight it should be done ghosting the line and confidently.

Organic Forms

You really nailed this one! You kept the forms simple, the lines are drawn confidently, the degrees of the ellipses and contour are changing, the contours are hooking, the ellipses are aligned, touching its boundaries and are drawn through. I just wouldn't draw so many ellipses and contours, just a few are enough to indicate the changing directions, as long as you keep changing their degrees.

Textures

Okay, this one is pretty tough. I see you managed to complete the main goal of the exercise which was to draw the shadow shapes instead of lines, you also didn't do any kind of hatching/dotting to achieve transition, and that's good. Yet i think the transitions could be a bit more seamless, specially next to the black bar, we can see it quite clearly.

Dissections

Again i think you got the idea of the exercise, you draw the shadow shapes instead of lines, you wrapped the textures around the form and broke their silhouette, so congrats! (although i don't think banana is a texture because it is pretty plain, i think you actually drew the black marks of the peel but i drew zebra skin before realizing this too so ¯_(?)_/¯) .

Form intersections

The only issue i see here is again the lineweight, just be a bit more careful and try to draw it exactly were the first line is.

Organic intersections

Okie, in this one you kept the forms simple and you drawn through the forms, so good job! But there's still a bit of line issues with some scribbling. Also i think you could push the shadows more so they really look like they are being cast into the sausage below. Most of your forms look like they are wrapping each other, there's just one that seems kinda stiff, but i think you got it. I'm leaving you a link to show how you could do this: https://imgur.com/a/b2ZdaTz

I hope this has been useful to you, again congrats on finishing the lesson and i think you did a great job overall!!
