Critique/Paintover welcome

[Anchimayen]

Hello people i'm new to this forums. So i'm an pretty much beginning artist and i have this piece were i'm proud of but there are some things i want to improve, because i can see it's far from perfect. The problem is that i can't seem to identify the flaws within the piece. So i hope some of you people can help me out, I would be very grateful.



Thanks in advance!
