Great focus and lighting. I would have preferred to see this pic a little more up and to the left to 1. fill the screen a bit more and 2. to see more of the light falloff as it goes across the ball.
The colors are nice here and I like the way you lit your subject. Pleasent placement in the picture and nicely framed. Reminds me of my childhood when we'd make rubberband bouncy balls.
This is a great shot. I love the lighting, and the colours. superbly caught. I can't really find fault in it anywhere. it's perfectly balanced between the negative space and the colour!
I had a feeling someone was going to do this. On the plus side, you have a lot of different colour rubber-bands, which makes it far more interesting to look at. And the framing is kinda cool, although it may be a bit too much negative space on the left.
A definite 9 from me; good colors, good lighting (good contrast with background), and something about the composition just makes it pop at me and want to be looked at. I bet people are going to complain about the texture on the bands, though. :->
