"The Shadow Knows". Nice use of light and shadow angle. I think if the shadow and ball had been closer to one another, might have produced an "arrow" or point effect to bring out the effect.
I like this. It would have just a bit more impact for me if the ratio was a little wider which could have been easily accomplished by cropping the top a bit. This would have also removed the dark distraction at the top edge. Fun thinking for the theme however. Good luck.
