Looks pretty sweet. If you want to make the pen tool look even better, just erase every other line, to make it look like it's really wrapping around him.

So say you start at the top and erase on both sides of the hand. Go down one line and don't erase any of it. Like, where you have the red erased on the second line, keep that part. And just repeat for the next two lines.

Sorry if that was confusing.
