Hello everyone, this is my first post, i'm very happy to be part of this community.
I'm working on a game where the main character is a dark child with powers.
I want to make it cute and dark at the same time, very dark.
So far i've got this:

Could you please give me your feedback on how to improve it?
I'm aiming of course for a 2d side scroller game, low to med res. Enemies should be 2 or 3 times bigger than the main character.
Also, it may look cartoonish but i'm looking for a more serious, close to reality model.

Thanks in advance!
