..Meh... Not bad
It was ok, the animation was good, and the style was nice, but the characters sucked. They were just coloured things, no shading, no clothes/apparell, no style. Maybe for the next one, put more effort into the models, and you're score would go from 6 to 8. Also, try and addd blood. But make it in a new layer so you can delete it easily and redraw it on the next frame.
