Ah, this is pretty sweet!
I wanted to ask btw... What was the preset on your smudge tool?

The cast shadow is a nice touch, but (on a completely unrelated aspect) the hands seem odd:
- Right hand: looks like it has only 3 fingers (possibly because the thumb rests on the middle finger like it would on the index, ie it's not far back enough + the index is not even hinted at)
- Left hand: is kind of claw-like. The pinky starts a bit far away from the rest maybe, and its metacarp seems too long; the index looks like it's dislocated or something like that (or it's some sort of thumb); the thumb also looks very long before the first knucle, too. Thinking about it, I guess that's a problem of the hand's perspective: the fingers are placed like the hand was resting on the hip, but the palm is actually lifted almost perpendicular to it.
