You know, this is actually pretty decent. Nice fullbody animation, an interesting black-on-white style with some red tossed in, kind of like Sin City... I feel like you're really onto something here. My biggest problem with this animation is that although the graphics are pretty good, with the characters having nice, solid proportions, the animation itself doesn't have much easing, and could have used a lot of improvement.
Also, the effect you used for blackening the cop car and the sound for the gun suggest you're trying to put a lot of impact behind the gunshots. It would have really helped if you'd done some kind of shadows and lighting to expand on the force of the gun.
Other than that this is really pretty good. It's really a shame you won't be able to continue this kind of stuff.
