good but not great
I really applaud your effort and ambition here. Obviously a lot of work went into this, and the basic story was good for a 6 minute cartoon. The scenes as conceived were well done from a storytelling perspective. But there were two basic things that kept me from giving you a higher score:
1. Animators really need to learn at least the basics of drawing before they start animating. There's a difference between a simplistic and/or cartoony style and an amateurish one. I'm afraid this flash is too obvious the latter. Perspective was especially lacking and really distracted from everything else going on.
2. There were some serious lapses in logic as well. Why was he doing the CPR compressions on her belly over her bullet wound? In the store, once he had a gun in his hand, why would he bother with martial arts stuff? And chainsaws aren't light sabers; there's no way that amputation would be that clean and easy.
