Could of been much better..
The idea has been done over and over again, but you did pretty well, it's very hard to make something like that and I appreciate your hard effort.
But, the fight scenes weren't that good, and it would of been cool if you did some REAL voice acting for them.
The camera quality also made it seem out of the normal, because the stick guy looked clean but the stop motion was just - yuck.
The clay guy was also super slow compared to the stick guy making it seem less alive and real. Then again, I've seen and even made, MUCH MUCH WORSE.
What I did like is the way you made the blood spatter and movements, though a little stiff at times it was acceptable.
You should take my advice and some other people's and try out on another one like that, I love stop motion VS animation movies myself as well.
