The music didn't really fit what was going on... it was a bit relaxed for hand-to-hand combat. You also had a bit too much of people just walking... for example, we don't need to see him walk down the sidewalk, and then down the stairs, and then past the guy. You can cut that chunk up much quicker. Lastly, the video didn't really have an ending, it just sort of... stopped. The music faded out a bit soon. The end is a good place to put credits or a final message or something.
I liked the shots that you got, a stabilizer would help but yours weren't too bad honestly.
I'd like to hear some of the sounds of the combat, it's sort of flat. you dont have to go cheesy mortal combat style, but a little something would add a lot.
