Good first attempt, but needs improvement
The graphics were very decent, I specifically like the grayed out blood splatter parts. However the two issues driving this one down were two things:
1. Story...I was very bored. Nothing much happened despite some very funny dialog and great voice acting. A story is the single most important aspect of any animation - "Pixar".
2. Animation. You can draw, but your animation is very weak. Really think about how a character would move, react, etc... Also look up what secondary motion is. Animating well is even more important than good art (example XIAO XIAO has no aspect of good art, yet holds it's own simply by amazing animation).
