First off, thanks for all the comments.
Secondly, I apologize for putting up an unfinished pic. The bottom guy is blocking the top guy's attack, which is why he isn't swinging his weapon. Silly me, it was late and I wasn't thinking clearly ... I was hoping each character would be critiqued separately ... but that doesn't really make sense in the context of a fight scene, does it? They're not making contact because the top guy is missing his weapon ... and I still need cheat a little by tweaking their angles on the computer. And yeah, the fact that they're not looking at each other was just laziness on my part - I was going to fix that latter.
Anyway, before it sounds like I'm making too many excuses for myself

...
Hmmm ... I see what you mean about his back, twotimingpete. Good point. I'm not too sure what to do with his left hand, to be honest. He's supposed to have just thrown a boomerang type weapon .. and is now pulling back that arm as he's attacking with his right hand. Initially I had his foot slightly curled ... but then I simplified it. I'll try changing the foot back to the way it was.
The more I look at it, the more trouble I think I'll have actually making their weapons make contact. Oh well ... I might have to change which arm the top guy is attacking with.
