The hand looks as though it was cut from a poster or something, the sizing or something is throwing me off, it looks off. The ball w/ effects is just that. . .I dunno. It's not bad, but, it looks kinda generic/hokey to me. Not crazy about all the dead space around the hand, I think if it were cropped tighter to the lines of the hand, it may work better, though I'm not sure what OP is going for.
I do appreciate the OP's demand: My pictures, comment about them. Lol, a very forward approach.
