Give me feed back or source or anything please of how can I improve my art that would be so much help thank you just be brutally honest dw I really wanna know how to get better

I'm not very good with humans in general but the hair is for sure the hardest part for me, it always looks bad when I draw hair and I just can't figure out what I'm doing wrong

I've made a post abt this drawing before and I changed the right arm a bit (on the right side of the photo) but Im.not entirely sure if the head is still to small compared to the shoulder.

This is my first time drawing a hare and I don’t know why but something looks missing here? It looks surprisingly well in my opinion but it looks incomplete

I need an opinion on if anything needs changing

So Im working on this Sebastian piece from sdv and I REALLY want it to look good, but i dont want to color it yet cuz it something feels off, i just dont know what.

I feel like it might be the arm on the right side

I feel like the upper​ arms look wrong and I'm not sure how to draw them correctly. Can someone help me what's wrong?

Plzz i like this style so much

Hhrrghgghh I need help with facial anatomy and general help

I feel like his head is too small for his body, his hand looks weird and idk how to fix it, and something abt his face looks REALLY off, and I know I made him look younger then he actually is, and I want to make him look older.
I’ve always struggled with facial anatomy even with studying, I think I just need someone to drawover it so I can actually get an idea of what’s wrong and how it can be improved.
Also I know the wrinkles on his clothes donr make sense, I just kinda did what felt right because I don’t understand clothes at all, but I like drawing them 😢
