It just seems like the sword is being swung towards the white guy, in which chase I feel like the empty space of the photo should be on the left side.
Here's a crude skeleton of the photo with the parts outside the photo I just sort of guessed on.

Here's the framing re-done on the left side.

Here's the shot slightly re-composed with the guy on the left blurred. I still think the guy on the right is still the focus of the shot and the shot seems more dynamic to me, especially since the guy on the right has color on the one on the left doesn't. (sorry for the bits of blue on the inside of the of the guy on the left and the general stufftiness, I didn't spend enough time to do it correctly).

It does definitely showcase your lighting set-up though, so that's good.
