I stared and stared and thought and thought about this shot. The coloring is so unique, and the lighting is perfect to convey the mysticism. My only issue is that while I like the blueish tinge on your subject's face, it seems to have gone too far. He looks almost dead. The only thing keeping it from being totally deadish is the eyes. Of course, that is probably what you were going for so...
Nice idea and the composition is interesting. The background works well also. The boys face seems just a tad soft, like he's this side of the focal plane a little and his face is also taking on some color hue from the ball.
I like your interpretation of the challenge and commend you on your originality. I think I would have preferred your hand not being seen. I also may have used a black background vice on with so much going on. Good job and good luck.
