I would rank this animation close to High-Beginner. The run in the beginning was very nice, and so were the camera movements. The attention to details ( e.g.: smoke puddles ) really added into it, nicely done.
However, the loss of speed at the end felt a bit... unnatural. It looked like he didn't have enough power to break through the floor, but eh, no biggie.
Debris, blood and physics at the end were pretty nice, as well. They all looked simple but to a very distinguishable fashion. I would advise you to work on your poses a little bit, and you'll be intermediate in no time.
