Good, but a little short
This piece does look excellent, despite the rather unorthodox (unoriginal) drawing style to animate with. The buildup was excellent and it looked good for the fight to start with. Sadly, since the fight lasted a few seconds, it made me thing that we had been slightly conned with the buildup being so long, for a fight to end so acrimoniously (See also Audley Harrison Vs David Haye for more info)
With the scenes where you were showing blurs behind the characters, consider working on those a little more, giving yourself a little more work that shows the blurs moving one way or the other, don't have them bouncing between two points, as if you had them streaming from left to right, the character gives the impression that he is running right to left.
When the one character emerged from the shadows, perhaps consider some other tactic, as he's not emerging from water. Yes, the light only reaching in so far is great, but I'm not sure it would look like that. Fade him in a little quicker, as he walks towards the light and it should look much better.
