00:18:166 ~ 00:23:949 - The rhythm choice of this section could be improved to follow the vocal more properly becuz you seem to follow the vocal here (like 00:22:503 ~ 00:23:226 - ) .
The first issue I noticed was that lots of vocals were missed. For example, the improvs on 00:19:160 didn't represent the vocals, and vocals on 00:18:618, 00:18:979 are omitted.
Another issue is about rhythm. Using 1/4 on 00:21:961 didn't represent the vocal well, I think you could consider changing it to 1/6. It could follow the vocal better in a simplifying way.
Therefore, I would suggest you stick more on vocals and adjust rhythms in some places to fix it.
00:35:515 ~ 00:58:654 - This section could be buffed to create more differences with Oni.
Patterns in these two diffs are too similar becuz you both mapped triplet/5-plets with some 1/2 patterns. So, I think you could add more improvs by following the vocal here to buff this part, it would help to resolve the density progression issue regarding Oni > Inner.
Also, I noticed that the density dropped suddenly in some places such as 00:39:672. You only mapped 1/2 here but the music is as intense as before, the density should be kept to represent the music properly.
For the above reasons, you could buff this part by adding a note in the following places: 00:37:051 - 00:38:316 - 00:39:943 - 00:40:124 - 00:40:304 - 00:41:570 - 00:42:112 - 00:42:654 - 00:43:196 - 00:44:461 - 00:45:365 - 00:45:907 - 00:48:618 - 00:49:883 - 00:51:509 - 00:51:690 - 00:54:401 - 00:56:570 - 00:57:473 - 00:57:654 -
