chess piece

I would like to get feedback of structure of my drawing and shadows which I know are bad.(Btw this was drawn from real life reference not photo) Thank you in advance.

Congratulations get the hair right

Please help with my cylinders:(

I tried to avoid too many lines. My cylinders looks a bit off… is it very important to get them super realistic to be able to draw characters? What should I aim for……

I'm confused as to what's wrong with this work. It could be the perspective, the form, or the shading of the characters.

Feedback on head study

I did some rembert montald study recently and i try to apply what i've learn from that study but i don't know why after learning some new hatching thecnique and did some Skull study i still feel the head is a bit flat, any tips to make the head a bit more 3d??

I think the nose looks a little wrong and the other parts have something wrong but I can't seem to put my finger on what exactly is wrong

I'm a beginner

I'm not sure what's wrong with the proportions of the face
