This is definetly the first stop-motion flash I have seen, and it isn't bad. I see two main problems with Ultimate clay fight. One, it's too short. Two, the lack of sound. There is no sound when any of the charectors recieves what should be a very painfull blow. Also, your stop-motion technique needs a little practce and refining, but it isn't bad. Keep practicing, and I will definetly enjoy your future work.
