(please see #4882228 first) the main concern i have is that the 1/2 xxx x xxxxx
rhythm throughout the kiais is quite repetitive
i understand the vocal rhythm does repeat itself so some repetition makes sense, and you indeed do variation by having varied patterns, but i still feel varying the rhythms would be nice to make the map a bit more interesting - see the following ideas:
[1]
00:59:895 move to 01:00:355 - since the vocal is kinda different on 00:59:205 ~ 01:01:964 compared to 00:52:309 ~ 00:58:286, you could vary the rhythm slightly to reflect this
similarly you could consider moving 01:47:711 -> 01:48:171, 02:02:423 -> 02:02:883 (and similar for the last 2 kiais)
[2]
01:54:377 ~ 02:05:412 - there's an added vocal here compared to 01:39:665 ~ 01:54:377, thus the mapping could reflect this change
maybe try increasing the density a bit by adding 01:57:826 02:01:504
[3]
02:40:355 ~ 03:02:423 - i feel it would be best to do something other than repeating the xxx x xxxxx
rhythm here to vary this instrumental section with the kiais that have vocals
perhaps try following the guitar rhythm more closely, for instance the following kind of rhythm is heard throughout and could be implemented: (first note on 02:40:355)
[4]
03:24:492 ~ 03:35:067 - this is arguably the most tense part of the song, having the most vocal layers, so you may even want to increase the density even more compared to 01:54:377 ~ 02:05:412
for instance, given how low the bpm is, i feel 1/2 7-plets could work nicely here to representent the climax of the song here (i.e. add 03:27:481 03:31:159 03:34:837)
kiais: right now there's quite a lot of 2/1 breaks in the kiais, which i feel is making the density of the kiais too light since the continuous mapping is quite short
this is particularly evident when comparing with sections like 00:10:469 ~ 00:16:906 say, which is arguably more dense given the higher continuous mapping despite being much less tense than the kiais
consider the following to better contrast the density between the kiai and non-kiai sections:
[1]
in the verses: maybe tone down the amount of 1/2 5-plets so that there's more contrast in density to the kiais, which use 1/2 5-plets (e.g. delete 00:14:377 00:21:274 01:09:090)

in the kiais:
