too much grey and white doesn't seem like a full b&w for some reason and the right side doesn't sit too well with me do some more effects or even a bg like you did on the left and it would look a lot better bring the text over his shoulder maybe solid
Don't stroke text, and no matter how street or hip hop, graffiti font ruins tags. It's position is bad, I would've made a straight cut over his shoulder and added a custom shape like a gunshot or a bird. (Byrdgang.) I like the duplicate face idea, but the delivery is really bad. I don't like how his chest is blurred, and I think some foreground effects wouldn't be a bad idea. The street for a BG is a good idea, but still kinda boring. Nice effort though,
