00:04:765 (4765|3) - this should end on the blue tick to be consistent with 00:06:848 - and 00:03:515 - etc.
00:24:556 (24556|0,24556|3) - im curious about the intent of this vocal use of double notes.
00:24:140 ~ 00:43:306 - no double notes are used for the vocal during the duration of this part, only double notes focused on the instrumental expression.
i would suggest removing the 00:24:556 - 4col notes, as this could be a consistent issue if this is not your intention.
00:32:890 (32890|0,33306|0,33723|0) - in my opinion you can structure this section nicer to avoid repeating col 1.
i dont see the problem here ngl, theres a high pitch sound here same as 00:50:390 (50390|0) -
01:03:931 (63931|0) - This part can be rearranged to flow nicely and also to follow nice vocal PR.
01:18:723 (78723|2,78931|1,79556|3,79765|0) - for the current vocal LN, 01:17:056 (77056|1,77265|2,77890|0,78098|3) - which has a mirror pattern of the vocal LN directly below it.
so, if move this piano sound to 1col at 01:19:140 (79140|3) - it will be more symmetrical and have a cleaner pattern at 01:17:473 (77473|3,79140|3) - which is what u want.
