i think it's fine since it follows the vocals imo + it's done all across the map, not just in that place. but i'm also not kurboh and i wouldn't know
02:15:391 (2) - can't see why you would add this note here since song didn't change at all from 02:13:933 and 02:14:662 i can maybe see that this is just for a little build up, but its unnecessary cause the song itself does not build up there
