I agree w/this... but I do sort of like the collage idea/concept.
I wonder how it would feel if you switched the 2 left images.. put the face on the top. I don't like how that cement comes out of his head the way it is now.
btw did you know this guy? or jsut come across him and ask him if you could shoot him? I could never do street phtoography, I just don't have the balls to walk up to people like taht.
