Here is my attempt on accurate portions. I had a lot of trouble with this, the overall shape is quite a bit off. Feedback would be very much appreciated.

I hate circles

I tried my best to simplify but i think I overdid it.

KEEP IT SIMPLE STUPID!

I decided to study Claudia Tuci. The way she draws nature is insane. I tried to draw in chunks instead of tackling the whole picture. It's hard for me to replicate a style so unique but I tried my best. Any and all feedback would be very much appreciated.

Very inspirational, I will try my best to always be aware of the the feel, weight, and purpose of the lines I'm putting down.

I mainly wanted to study Watt's very confident loose line work. I had zero focus on portions, shading, or style. I tried my hardest to focus on good line quality and confident lines. Feedback would be very much appreciated.

I think I did a decent job on the Hierarchy of importance method (first photo). The Shadows and light direction method is quite hard for me. How do I improve?

I really enjoy this, have fun everyone !

I tried my best to draw a good representation of the thing I was drawing. I had a very hard time with the VR girl. My positional representation really needs work.
