Needs Colour ><
Graphics: All the characters were sketched pretty well, and the little FBF and gunfire you did was done pretty well also. To really up the votes I do think it needs colour though, and try to do some voice-character syncing.
Style: Most of the animation was single sketches, like a fast slideshow, so maybe you should try FBF animation, otherwise, this wasn't the best animating I've seen =\
Sound: It synced pretty well, but try mouth sycning.
Violence: Pretty random and all over the place, which isn't bad I guess lol
Interactivity: None
Humour: Most of this was pretty random, especially the joke that led to getting shot in the face.
Overall: This was not badly done overall, but voice syncing and colour would definately help this flash go along, and give viewers more interest.
