the entire picture is very messy. I doubt this was a posed shoot and more of a snapshot as it happened. I feel it's ok for documenting the process of growing up just to be filed up, but I don't get any feeling with this picture.
You might want to ask, what are you trying to capture in this picture before taking the shot. Rather than find a reason what the picture means after the shot.
Although most of us (including me) do the latter most of the time.
