Personally I feel that the action goes too fast. The specific fight moves don't get a chance to stand out.
Also I would've liked to see more dynamic shots. Now you've got what my old teacher used to call a "puppet theater" effect going on. Try using a close up or two in the action, have a single big movement go across several cuts (while maintaining the fluidity of the motion.) Further, I'd try to put in a break or two between bits of action.
