The Model
The model doesn't look so good at all, sorry. When in motion, the knees go out of place, the glutes go out of place. They look a little bit bulky. Try using Rich's ToriRig, it looks good.
The Moves
The moves look realistic and creative, nice job on that. Again though, when in motion, they do not look so good. Most of them do, but parts like getting up and rolling do not look so good.
The Movie:
Some effects do not look so good, such as gravity and speed. The gravity is fine. but the speed, as said by earlier posters, does not match up to close real time or even close 'Toribash Replays'. You might want to add blood(metaballs?) and the bruise effect like in toribash. Well, blood wouldn't really fit in a fight, unless it stays onto the tori and uke.
Goodjob overall, seeing that this stuff is very hard and I have no experiance at all with this.
