Nice
DaSaint is a moron. Obviously he hasn't seen many animations. Your art needs a bit of work, but it's hardly crap! There are a few things I noticed and I'll point them out so you can fix them if you wish since you seem to want to make this a hit of sorts: hands (characters have palms, don't make the finger extend into them), shoulders when walking (when you walk your shoulders don't move back and forth as much as you made them. Look in a mirror when you walk to see what I'm talking about) and blood has diffrent shades of red (remember dark to light and visa versa).
But the things I pointed out are common error's I tend to see (I take an animation class at school so I see over 20 peoples other work when we have presentations). But your character designs were well done and the plot looks very interesting^^ I'd love to see it when you've made it.
Good luck with its creation and perhaps what I've told you can help.
