i still think this should have finished higher than it did -
the shapes you captured with negative space are great! -well back to my post-challenge commenting! :)
This is nice, but my attention is drawn to the balls, not the hand. <---If I was 13 again I would be laughing like Beavis and Butthead about that line.
Neat looking, though would have a bit more impact if it were a little sharper. The fingers and the balls seem a little soft. Focus appears to be at the base of the palm.
I can't quite tell if it's motion blur or just slightly out of focus. I think it might be the former. I guess my advice would be to try this again in an area with loads more light so you can bump up the shutter speed. I really like this, just a shame about the blur.
