You did great job with the perspective.
vector is excellent, great job chloe-chan.
vector of background is great too. but there are two things that bother me.
why is the street light in the front smaller than it should be, and one in the back is the same size?
also "animepaper" graffiti is lowered and it bothers me, who would write graffiti so down on the wall.
but this is really great and deserves attention. Its Hayato Gokudera btw.
since you did excellent job and done perspective well, and since he is my fave, im putting it to my faves.

You are getting more and more better in vector styles, and also thanks to Cloe-chan for the vector :P Background is made great, the only thing what I could mention the closer streetlight, it's a way too small, and trough the perspective should be even bigger as the rest.
Still a good one. Great idea with the AnimePaper graffiti :3

AWGAWD Gokudera is so hot LOL. This is an interesting gray scene! But Gokudera doesn't look well with the background because he looks like he is drawn messily and your background is really neat.

If you have a tablet, I would suggest you draw the background by hand, even the straight lines because walls and sidewalks and such shouldn't be clean and straight. That will make it match Gokudera and it will also make it look more rebellious looking because everything would be dirty, hehe. Well, not dirty, but messy.

I also think that the brick wall is at the wrong angle, because it's kind of confusing looking behind Gokudera. I think the bricks on top should be bigger and the bricks to the left should be smaller, but I'm not sure.

Oh, about that comment about the graffiti being too low, I myself have see a lot of graffiti at the bottom of walls, so I think it's fine. Some people like to squat when they vandalize, lol. Anyway, good job on this wallpaper!
