Personally would've had the melodic instruments like the santur a bit louder in the mix as they felt a bit under the percussion and pads at parts.
The choir pad with the percussion and the piano sequence gave me a lot off same vibes as the music from Final Fantasy 10, not sure if you're a fan of Masashi Hamauzu but you managed to evoke a lot the same ambiance they did in that, just a really cool atmosphere all around.
Good work!
