Please add a play button.
Behold my surprise when I "alt+Tab" back to the animation after doing something else while it loaded and it was already well into the action.
Many people, like myself, will do something else while an animation loads, so you need to include a "play" button so they can choose to start the animation at their leisure.
Also the sound was very, very quiet, I have my speakers plenty loud because I've been listening to music on my computer, I stopped my songs so I could her your audio, I didn't even think their was any at first, but then I heard the faint, faint music. Unless your aiming for barely audiable sound, which you very well could be, I'd advise making it louder.
Other then those to problems, very nice animation, fluid, active, very well animated fight scene. Good job.
