Nice ones up. I especially like the black and white one. It has a nice blend to it. Although the sleepijs text may be a bit out of place try and make it overlay effect so that it can blend in more with the wall like a spray paint type of thing. Also I noticed the Avenged 7 Fold (A7X) :D. Also try and fade the render to make it like a graffiti art you get what i am saying. But overall great work.
