A few things
I think that the setup and story so far is genius. However, the drawings of people looked a little rigid and with no curves. That really annoyed me thruout the whole thing. The city looked like a bunch of squares that were lined up in some sort of order with a sidewalk. There were no streetlights, signs, or people walking around. Lastly, your switching from brush to line all the time messed with the whole thing. Like you couldn't decide what to use. I suggest sticking to one or the other from now on. Oh, and that whole thing where the song pops out of nowhere when the guy is being blasted to death was out of place and took the mood away. It made the guy's death need less climactic and it went to other scenes where it was also out of place.
