Beautiful composition work here! You really put these instruments to great use here. I especially loved that no particular instrument stayed the focus overlong so every point of the song feels fresh across multiple loops. And speaking of that loop, I loved the way that the loop ends with silence. It's a nice reprieve that serves as an end point well, but somehow still feels seamless when you loop into the start. I honestly don't know if that was intentional at all but I've rarely actually encountered a song that utilizes a clean ending to its loop like this. Off the top of my head there's Meridian Dance in Secret of Mana? And that did it in a completely different way.
Kudos
