I'm sorry for my comment yesterday it was out of line, rack it up to a very bad day. As far as your image goes I feel it's too dark with bad lighting and little interest. Sorry if that offends. Composition is alright and the idea of the use of dead space is interesting but it definitely needs some work.
I think the ball should be more in focus. I know it's difficult (at least with my camera) when there's low lighting, but maybe a brighter shot would've worked better. :)
The image would probably work better for me if there was some more light on the ball. The ball is probably suffering from motion blur here due to a slower shutter speed under these lighting conditions. That does not really support the 'still life' idea when you think about it...
