Character sleeping in the woods

How could I improve/fix it? I’m planning on redrawing it so I would like to know what should I work on in the next drawing of the same idea

What to improve on values

Vodyanoy

A Russian water spirit that drowns people, lives in a lake and can transform into a fisherman. The water spirit seems a little uncanny in a way that doesn't seem intentional and I can't fully put my finger on. I'm sure the legs and arms are a bit off and I think the placement of the shoulders. Any critique of the design is helpful thank you.

Hallway

I can't seem to get the Perspective right. Even with guidelines everything seems a little off. I would also like for the Fisheye-Look to be more evident but it just looks weird

figure drawing progress

While this is not 100% finished, hands and legs still need polish I wanted to share this. There is probably still a lot here to fix and improve, but I felt very good about my progress with this one. This was the first time I felt 100% confident with every piece of the body from hair down to feet. There is a long way to go, but I felt good about the progress thus far. Considering everything, I think I nailed the perspective on this one.

demon girl

I drew this character from my imagination and I think it looks good, but are there any changes I can make to make it excellent?

Tigre che guarda l'orizzonte

I have a problem with the head of the tiger, how do you guys simplify it?

Mega Rayquaza as a human

The revision and revamped concept. I did the after as a draw over, but now i am resubmitting this as a revision, just to make it easier to understand and see and stuff. More details on the drawing are on the revision

What do you think I could fix/change?
