Mr. Perfectly Fine (Taylor's Version) (From The Vault)

00:19:235 - to avoid going with 4/1 rests i'd place a note here, you could do the same to the rest of this section like:

• moving 00:22:323 to 00:22:764;
• adding a note at 00:29:823;
• moving 00:32:911 to 00:33:352 (would have to remove 00:34:235 so the layering is consistent);
• and adding a note at 00:43:941

doing this would make this section flow a lot more nicely and it also transitions well into 00:45:705 onward

same idea for 01:32:029 -> 02:00:264 but adapting the structure where possible

03:06:882 - adding a note here to follow the same structure idea would be nice as well

00:24:529 - the layering on this dkkdk looks a little weird because you're trying to follow two things at once, you could remove this so it plays the same as 00:38:205, if you want to focus on the vocals you could remove 00:24:088 - but you'd have to account for later uses as well

00:28:058 - Add k here to vocal flow and cover drum sound. Personally I think there are so many 1/1 3plets around this area, and quite boring to play. Some 5plets are very good as build up pattern.

00:32:911 - Consider add a note here as build up pattern. There are so many gaps for your current pattern, and I think this area have continuous sound so it's better to add a note.

00:58:499 (77,78,79,80,81) - 02:12:617 (182,183,184,185,186) - the usage of 1/2 here is so random and kinda jumpscary for player. i think you can increase density normally by just doing xxxxO (so, ddddK for the first instance and kkkkD for second)

00:58:499 - (Same timing as Amasugi) but I won't re-open it.

Consider change 5plets as kkddk since the 1st & 2nd note contain instrument sound, and vocal pitch is higher than 3rd & 4th note.

00:59:823 - i know there's a vocal here but since the instruments fully stop i think it could be nice to remove this note, it would also be a nice consistency for the spread to futsuu

same for 02:13:941

01:01:146 (82) - maybe move to here 01:02:470 for rest moment, since you don't have any rest moment for 92/1 from 00:45:705 -> 01:26:293

also 01:15:264 (103) -> 01:16:588

01:01:588 - This is place where the vocal is start ("Mis"), so consider to move the 1/1 5plets you place at 01:02:029 - start from here, then change to dkkdk to match the vocal flow.
Then you can add d at 01:04:235 - and change next note (01:04:676 - ) as k to optimize it.

01:07:323 - i'd move this to 01:07:764 to layer the vocals in a bit more nicely since you already did this on 01:21:882 (you would have to remove 01:09:529 like you did it in 02:23:646 to accomodate it though)

02:21:441 -> 02:21:882
03:53:205 -> 03:53:646 and remove 03:55:411

01:10:411 (96) - move to 01:09:529 to form a 5plet for some density here, and also some rest time before finisher chain

01:23:205 - i think moving this to 01:22:985 would be nicer to the structure, you already follow this in some parts where the vocal is not present it wouldn't hurt to do it where it shows up

02:37:323 -> 02:37:102
04:09:088 -> 04:08:867

01:30:705 (124) - i think this note could be moved to 01:31:588 because there's a small buildup overthere

02:49:235 - maybe add a kat here for a bit of variety on the patterning for this section?

03:01:146 - you should move this to 03:01:146 to stay consistent with 02:58:058, it also goes very nicely with the vocals if you also do these:

03:04:676 -
03:15:705 -
03:19:235 -

since you're following vocal maybe move 03:10:411 (254) to 03:09:529 to follow vocal more closely, and create a small gap before finisher

04:18:352 - same idea as other mods about vocals, you could move this to 04:18:793 and maybe even make it a 3plet with 04:19:235

adding a note at 04:20:999 would go nicely too, you could move 04:21:882 to 04:23:646 so you can still keep the 5plet as well
