Great capture for something that is going so fast and quick.

Little bit of dead space on the right. Perhaps cropping a little tighter? As these men are trapped in a "cage" while fighting. Cropping tight might give a more claustrophobic feel.

And it's a shame that you can see the outline of the fence that you were shooting through.
On one hand, it tells the story of where this image was taken. On the other, it's a slight distraction. So, I'm not sure on it.
