Whoa, nice.
First thing's first: My compliments on the total, it turned out really good. But.... A few flaws here: I think you overdid it with either the quality of the background or the quality of the sound, or both. Flaw number two: The all black figure thing might be good for the intro, but some color (doesn't matter if it looks like some crappy gnome or a messed up version of tricky the clown, just something!) would be nice. That is all I guess... Oh, and I see you drew the intire scene with the brush. How? Well, you missed a few spots on the roof of a house. A more failsafe way to do this is to draw the outlines and fill it up.
