Studying value organization with that one checkered optical Illusion.

I find myself overthinking if the values are light or dark enough. God help me if i have to start coloring.

Dress drapes

I'm having trouble creating the "spiky drapes" at the end of her dress, especially at the front ; also the skirt is meant to be very tight around the thighs and pelvis/waist, are the lines right here ?

Figure drawing

I tend of having a bad habit of making the head sometimes too large on my figures and I struggle connecting the rib cage with the head. Also some inconsistencies with the limbs as well. You can also include any other things that I need to work on.

Ship and waves

I dont know how to improve it substancially, maybe the waves look weird?

MONKEY

I am struggling making this monkey have powerful impacks on the ground if you any suggestions that be helpful.

3 values study

This my 3 values study, is there any mistake or anything I can improve on? Since I couldn't find my own mistake. Thank you.

First colored portrait

This is my first ever colored portrait. Feels like my values are way too light, wanted to make it darker but I just can't get it right. The ear is kinda bad, didn't take my time there it was mainly a coloring/value focused practice

Drawing Faces

I’ve been practicing drawing for a year, specifically faces. I feel that I have improved a lot, but often my drawings seem out of proportion or with the perspective poorly made. I have a hard time finding the right angle for my eyes, despite practicing Loomis. And the features often feel out of place. This particular practice has lasted 30 minutes (5 minutes per head), and I tried to stylized it a little bit, but I would like feedback on which things to prioritize when representing the angle of the head and its features. Thank you very much!

Leonardo (the turtle one)

Lines values and forms a bit off I think.
