I think this is at most a pre-battle. Or maybe a very civil battle with very minimal fighting going on. You set the atmosphere right (again), but there isn't that much else going on, I'm afraid.

Good but...

I truly liked the song, but it was WAYYYYYYYYYYYYY too muted and quiet to be an epic battle song it seems like background music for when the adventurer is in a common battle or just traversing the world (Oblivion comes to mind here)

You need to work on your build up so that it has more of that awesome epic battle feel; mabey more choral and orchestral rises?

cool

I think it's good for what you're trying to accomplish. It definitely captures that "end of level" theme. Or the "epic final battle". Great job.
