My, that's alot of blood.

I don't like some of the bits of destruction you added in, the chunks of the sidewalk are far too repetetive. The building? I like the building, great work on that. Alot of the cracks (most easily seen on the big chunks laying around) don't look very good. The lines are too bold and too solid - make them fade as they get thinner or...something...*shrug* I don't know of a tutorial or reference piece off hand to throw your way.
How did you get the lighting of the screenshot to be the way it is? Or was that screenshot edited?
