Needs to be colour this. Thought about this for a few minutes, and can think of no reason why this should be black and white.. other than you liked it of course. Someone noticed the white blobby pattern behind his head in shot 2... well that would be less of a problem if you introduce colour maybe.. depending on what colour the graffiti is.
I agree with cropping the fingers off. Either in or out..... but halfway through fingers or foot etc just looks like you didn't make any effort when you framed the shot.... or only concentrated on his face and paid no attention to the rest of the frame.
