You could do better than that..
it wasn't very good..but i think you could do better. It seemed like you didn't wanna spend alot of time on the animations. For example..when someone would get shot..it looked like all you'd do is take the layer you used for their head..and rotate it maybe 20 degrees as their body fell..to make the impression that they were collapsing, rather than animating their whole body. Also..it was too slow, like every bullet was in slow motion. Not to mention..even when the bullet was in slow motion, and moving towards someone, they'd inhale and exhale like twice before the bullet reached them, so the timing was off. Put more thought and effort into your next one.
