Since your main focus for this section is on the vocals, I would suggest removing the notes for kicks, which would be consistent with 00:29:704 - cuz you decided to follow the vocal on 1/3 instead of the kick on 1/2.
These are the notes I would suggest to remove:
00:29:704 -
00:32:991 -
00:34:669 -

after 00:38:026 - the notes should not be removed cuz switching the layer to drums make more sense to lead out this section.

If apply, make sure to make similar adjustments in
01:21:033 - 01:32:361
as well for consistency.

Just a reminder, all SV concerns mentioned in this diff should be also applied in oni as well.

Stuff like 00:15:363 - 00:17:042 - are quite questionable cuz the vocals are broken and not actually snapped on 1/2. imo the current 1/2s are not really fit with the song cuz there no drum or anything to follow.
If you want to follow the vocals, then I would suggest moving the notes to 00:15:416 - 00:17:094 - (1/8). Otherwise, I would suggest sacrificing the vocals and make some more focus on the drums instead by moving them to 00:15:573 - 00:17:251 - and so on

Chains like 02:55:014 - 02:58:370 - would be a bit overdone, consider removing 02:56:167 - 02:59:524 - and so on

Overall SV concerns
Your overall SV currently are too overwhleming. Not saying they are too fast, but the changes are too excessive.

Using part 00:13:475 - 00:26:902 as example,
The song is not like super calm here, using x0.5 is definitely too underwhelming. Usually I would use x0.9 for part like this, but x0.8 also works.

Here are my suggestions about adjusting SV for sections:
I. 00:13:475 - 00:26:902 x0.9
II. 00:26:902 - 00:38:65` x1
III. 00:40:328 - 01:07:181x1.1 or x1.2

01:07:811 - 01:20:608 -> (I)
01:21:028 - 01:32:356 -> (II)
01:32:356 - 02:00:888 -> (III)
02:00:888 - 02:14:314 +0.1 based on (II)
02:14:314 - 02:27:531 x1
02:41:167 - 02:53:335 x0.8 / x0.9
02:54:594 - 03:21:237 x1.2

Please note that the suggestions above are rough ideas about the SV for sections, not included some smooth SV like 00:52:286 - 00:53:755, so make sure to change these special gradually increase/decrease SV chain as well when applying this mod.
You can also buff the values above, but remember don't make the changes between them being too drastic
