I have two major issues. I'm stuck trying to figure out what the green item is in the hand, and I'm distracted in the detail of the fingers compared to the editing in the back of the hand.
Fun entry, but it suffers a fair bit from motion blur. You've lost some texture in the skin too and it almost looks like paper mache. Suggestion; try again with more light and a higher shutter speed :)
I don't know how you processed your picture. I see some very distracting streaks on the left side of your pciture. It seems as if you selected the area between the thumb and the pointer finger and then burnt/overlaid what ever was there.
