Very nice. The sound is pretty good, all instruments come out nice and clear, big plus for that. The piece itself to me sounds more like a preparation for battle, than the battle itself, because you know... in battle music, stuff tend to go crazy really fast, lots of very dynamic percussion, super fast string ostinatos, a soaring brass melody etc... Hope you know what I'm getting at. This is great, I especially like the low end brass, is that from EWQL? The bells are a really nice touch too. All I am missing is pretty much a memorable melody line, but it works really well like a build-up to something with a large orchestration like this.
All in all, pretty good job, if you continue it and do an explosive middle section with an aggressive coda you got yourself a pretty epic piece.
