Very nice composition, color and lighting. It is not as colorful as some of the other entries but has more drama from the lighting then several. Did you shoot a version where you can see your eyes? I can't decide if that would help or hurt this picture.
Wit the composition the focus seems to be more on the kid... the glass ball doesn't really have any serious bursts of color either, just a few darkish swirls... if the light had been colored then maybe, but this doesn't reach me like some of the other photos do.
