Cinematic.
It was good from start to finish, largely because you used a few devices that you rarely see in things like madness combat (although to Krinkels' credit, he gets more cinematic every time). Realistic smoke and blast damage, slow motion, point of view shots, and use of lighting and contrast in those silhouette shots elevate this above random violence and raise the bar for future animators. It's an exhilerating action sequence.
As just one criticism, the character's movements seemed kind of jerky sometimes, but it was all minor. I guess I was hoping to see more the kind of seamless motion you showcased in those silhouetted shots. I haven't yet acquired Flash, which I mention to admit I'm not in a position to judge. I know it's more difficult than it looks, and minor jerks are justified simply by the amount of movement you had going on at once. Taken as a whole, it was very smooth and realistic down to every crouch, fall, and lunge.
Oh, and I dig the extras. Fight on ; ]
