Nice
Love the darkness and contrast... Looks dirty like you said.
It kinda looks like you're in some kind of lonely structure out side of town, and looking at the city as if your life would be better if you were there... A pretty sad drawing in that way IMO. :(
The buildings on the right don't seem to fit in though... So I'm not sure of what's going on.
Awesome style A+ for that. It's a cool drawing!
