The graffiti in Photo 3 is so nice, it would have made me take its photo, too, if I had seen it! I think, well sprayed (3-d effect) graffiti is a piece of art of its own, it really is. (I'm not talking about tags).
I like #1. Only because I am particular to more of the art in graffiti than just words. The way that they can make art like that with spray cans is really neat.
