Just seems kind of random. if you had picked a more uniform situation like a line-out for eg and then looked for one shoe 'out of place' as it were, or doing something different, then the sport theme in this shot would have been much more powerful. Or if the randomness was what you definitely wanted, then a pile of bodies after a big tackle with shoes sticking in the air and all over perhaps?
This is a hard one to rate. I love the idea and although I like the overall composition, I wonder if a tighter shot/crop would have yielded a better image. The center movement is a bit distracting (not much). It's there....somewhere.
Ha, interesting photo. A bit too much noise. I like the action and momentum here. To bad I don't like football. I think this would be better if the border was thicker.
