nice sculpt and the blending/OSL is done really good.
but the strong lines/rapid stops used to end an area kills the face for me. Most noticeable on the cheekbone. I mean I've never saw a human where it separates that whole part from the face that much.
I don't know if it's only the painting or the sculpt itself, but you sure made it noticeable.
That was from a 'realistic' standpoint. Taken as a comicbook figure with a comic style it's ok.
