I like everything about it except for the staged graffiti. I suppose you felt that unless you spelled it out in short words and big letters, most voters would say 'Huh? Where's the Dead End, dude?" Sadly, you're correct.
Anyway, the wall, the guy, the window, the title, the composition and the technical aspects are terrific. Delete the words and it's 10. This way, 7.
I love the guy's expression. He seems thoroughly ticked off. The spray paint sure is nice and tidy for "graffiti" but no fautl for that. His placement in the shot is perfect to showcase the words. Love the old brick building as the backdrop. If indeed you found this and didn't spray paint it yourself - WOW 9
