I feel the artistic element in this shot with your post processing. You probably are getting a lot of comments on how this isn't street photography. While that case can be made, the shot itself is good.
Hmmmmmm I would hope to see more in a street photography challenge... perhaps a shot like this would have worked if they had some sort of strikingly different pair of shoes but thats no really the case. Also I am not sure about the over processing of the shot, it lost alot of quality, overexposed some parts... but at the same time it did caught my attention and the more I look at it the more I open my mind to appreciating it =)
Good use of shadow, though I can't quite figure what's casting the one next to the closest set of feet. I like that this appears almost to have been shot through glass - was it?
