Hi! Good job on completing the lesson. Here are the things I want to point out:

Arrows: You have the right idea. However, I notice your lines wobble and don't follow a swift trajectory. This breaks the illusion that this is a flat form. Also the twists in the arrows look awkward sometines. I can see you get the idea of this excercise, so focus on making sure your lines are confident.

Organic forms: Overall, you did well with the ellipses and the contour lines. However, the sasauge shapes don't look very solid and you elongated some of them quite a bit. They are supposed to be solid simple organic forms.

Texture: You did well on these. I see you understood to draw cast shadows. For the dissection excercises, you could've done the transition from dark to light with your textures, and some of the textures don't seem like cast shadows and just look like lines you put down. Many people tend to get tired on this excercise and make this mistake. I also noticed on the scale texture that you didn't wrap the texture properly around the form, and the contour of the shape is flat. This makes it look like an imprint on the form insteaf of actual texture that is ocuppying space. Make sure you work on that. Also, I have to mention the same problem with the elongated forms.

Form intersections: These look good. The forms look solid and their sizes are consistent. And good job on trying the intersections aspect of it.

Organic Intersections: The forms look solid for the most part and you did a good job piling them together. The shadows also look pretty convincing. Just remember once again to avoid the mistakes I mentioned before with the sausage forms.
