Gorgeous orchestration! Super mellow to start out but it really starts to take shape around the 1/3 mark in. Great choice of string articulation here and leaving some room for the bell-like melodies to breathe in-between the swells. The gradual introduction of kicks about 2/3rds in to establish a rhythm and then having the other elements play around that is done well, and the building crescendo into the ending was really nice.
Enjoyed listening to this, I think as a whole it is arranged well and really fits with the write-up; I can just envision hearing this in the background of a cutscene revealing the spirit world. Great work. :)
