staged? snapshot? either way... its a kid, and not a baby (guessing).. in my opinion too old and not yet old enough to show private parts. and the shot is plain and looks like a regular old snapshot and not an entry for a photographic contest.
This really doesn't do anything for me. I see your subject is in focus, and the lighting is good. But this still looks like someone just dropping trou for a pic. I'm giving a 5 because it is not a blurry snapshot.
Great idea for the challenge! Very cute and funny at the same time. Could have used some more imaginative lighting though. A couple of lights on one side and a reflector on the other for fill and this would have been cooler!
