Fairly good.
The effects were excellent, I'll say that right off the bat. However, to be critical, the physics were a little bit off, an example being when one of the stickmen ripped the pillar off of the ground. The fighting was smooth and pretty well-done, although the big 'let's punch the shit out of each other' segment bothered me for two reasons: It was a loop, and their arms stretched.
Maybe this is your style, I haven't watched your other animations. My only final comment is that the stickmen were a little squiggly, but you probably draw them with a mouse or tablet with the paintbrush tool, or so it would seem.
Anyways, all in all a good, solid stick fight. If you improved those things, you'd have a masterpiece on your hands. 8'd and 4'd.
