Good work
I like this a lot, but a few things I have to critique are:
The lettering. It's some odd rendering and kind of pixely at the edges, and it doesn't match the rest of the piece. It just seems kind of tacked on.
and
The right hand (His left hand). His thumb would be over his fingers, not under them. Just a minor detail really, but I am a picky guy when it comes to drawings of hands grabbing things.
I DO like the pose though, and the colorings not bad either..
