Very nicely^^ I really like this piece of art. Design and coloring looks truly awesome. But I think you made mistake with his left hand. It looks a bit wrong for me. But anyway, great work with this one
The special effects are pretty nice, given the theme; the twisting and churning is pretty good. I think what would have worked even more is if his eyes were more pronounced. Whenever I see scenes like this, the eyes are usually emphasized in some way. You did a good job on the perspective.
