This is really nice. I think there's some lack of realism with the lead instruments at points, and the backing instrumentation can feel a bit repetitive at times, but that's all I can really complain about. The melodies are lovely, and a lot of the areas of the production really shine. I love the cymbal crashes specifically, plus the timbre changes on the lead instrument. 1:35 e.g. is a really nice moment.
Definitely sounds like an awesome battle theme to me :D
