Interesting character concept.
the white strokes/outlines around the hands that are overlapping the demon looking thing's right leg could be thinner, or reposition that leg &/or arms, so that right leg was a little more visible cuz right now it kinda looks like a bunch of broken up lines in that area.
This'd make for a pretty awesome animated character tho. Same goes for most of your other pieces too! Ever try making some stylized environments to go with your characters?
