02:11:610 (1) - remove NC?

01:28:904 (1,2,3,4,5) - Maybe you could move it a bit righter? because 01:27:492 (1,1) - got overlapped and on current AR this may confuse players to read this part.

01:38:257 (1,2,3) - I think you can also make alternative variant of the rhythm to make it a bit simplified? and also being a bit different from the top diff and follow rhythm more accurate.

01:49:551 - same thing here

01:59:080 - 2168699#4872850 same thing here

01:26:080 (1,2,3,4,5,6,7,8,1,2,3,4,5,6) - I think you could add more spacing for these jumps for more engaging gameplay?
02:33:845 (2,3,4,5,6,7,8,9) ; 02:37:021 (2,3,4,5) ; 02:39:492 (2,3,4,5,6,7,8,9) - if you compare how cursor is moving here during 1/4 slider in those sections, it looks like a bit underemphasized, so giving a small improvement here would be cool.

01:59:080 - This chain is kinda a bit inconsistent of using 1/4 rhythm, the fact that it starts from 01:57:139 and have small amount of 1/2 gaps here, I would like to suggest add here these gaps too to make less dense rhythm and make it less "overload". I mean, 01:57:139 (1,2,3,4,5,1,2,3) vs. 01:59:963 (2,3,1,2,3,4,5,6) - are mapped different, and the second one mapped much harder, but the moments are kinda same. Small reworking would be cool here.

01:38:257 (1,2,3) - I guess this mapped a bit in wrong way? Because 01:37:374 (1,2,3,4,1,2,3) and 01:38:433 (3,1,2,3,1,2,3) - are currently have different structure which in result create a small misunderstanding what you trying follow to. I would like to suggest put here a slider 01:38:257 (4); and a bit rework second part with triples how you did before for making a consistency of rhythm in this moment. (To clarify: 01:37:551 (2,3,4) vs. 01:38:610 (1,2,3) ; 01:37:904 (1,2,3) vs. 01:38:963 (1,2,3) - mapped a bit different, but they are absolutely the same?
Same thing here 01:48:763.

02:43:727 (1) - 5% volume on slider end? Looks like you forgot to mute it here.

00:50:963 (1,2) - DS is probably broken here? (supposed to be 0.8x)

02:31:551 (2) - same thing here

01:38:345 (4) ; 01:49:639 (4) ; 01:50:697 (1) ; 01:49:639 (4) - Maybe remove these circles to not making such a long 1/4 chains here? For Insane diff it's might be quite complex for the players and removing this would not ruin the rhythm and also improve the gameplay a bit.

02:52:904 (1) - move this higher since overlap with sliderend might be looks a bit sus?

03:03:936 (1,2,1,2,1,2,1,2,1) - Suggesting to nerf this a bit, yeah I figure out that this is the end and you trying to maximize the jumps here, but making this full-screan looks more diff-spike and overdone. Just small nerfing would be enough.

00:33:305 (3) - Would you like replace this to two 1/2 sliders to not make a repetitive construction of 1/1 slider + circles + 1/1 slider + ...?, which is also might adjust vocals here more better imo. Also, suddenly dropping this moment 00:34:425 do not maintain your general rhythm idea as i see? So yeah.

01:23:827 (1,2) ; 01:27:740 (2,3) - This might be quite subjective, but I think current jump rhythms for vocals looks like here more randomly other than you trying to follow them, especially if we take a look how it goes later like 01:24:642 (1,2,3,4,5) or 01:26:109 (1,2,3,4,1) - where you mostly using such jumps for drums-sounds. Could you replace some of them with sliders? For example, 01:23:827 (1,2) ; 01:27:740 (2,3) - replace this with 1/2. It will also create a better difference with 01:29:044 this section, where you map with more active jumps.

01:33:772 (7,8) - Add whistles here for your additive rhythms? It's currently sounds quite empty.

00:17:305 (2) - I think this slider is kinda not really good fitting here as for 00:17:305 (2,3,4) - this pattern structure, since 00:17:631 (3) - new lyrics starts from this moment and small reworking on this would be good (same thing for 00:23:501). As example for 00:17:305 (2,3,4) - you could change this pattern to something like this:

for 00:23:501 (1,2,3):

This way of patterns will have at least some connection with the change of lyrics in the song and will better to highlight it.

00:25:131 (3,4,5,6) - I believe you could give more spacing for this, since it's still remains the same, while there are snares and drums.

00:35:240 (1,2,1,2,1,2,1,2,1) - These jumps are really huge in spacing for the beginning of map, when even the top diff mapped much lower in spacing. Nerf this please.

00:53:338 (5) - Remove this circle since vocals is also disappearing here?

01:58:718 (1,2,1,2,1,2,1,2,1) ; 01:48:283 (1,2,1,2,1,2,3,4,5) - These jumps are currently have huge spacing for snares jumps. Suggesting to nerf this for avoiding big jump between this diff and Insane, since Insane using sliders instead of circles (and jumps are also smaller accordingly).

02:18:120 (6,7) - add whistles for your additive rhythms.

00:21:381 - Maybe you could not skipping vocals here and add a circle?

00:33:936 - Since you usually trying to follow the vocals in song, I feel this rhythm might be better:

01:28:718 - Starting from here, I think you made the change a bit drastic, while the music does not changing too much. You increased SV and made more spacing here, which looks a bit overdone. Making such dense rhythm without any 1/1 gaps and bigger jumps with SV might be really feels like overdone for this. For the best solution, I think mapping this just with the SV 0.9x would be enough to show how this section has been changed.

01:46:653 (4) ; 02:41:436 (4) - I think, would be much cooler if you change this to circles for highlighting the snare-sounds here.

02:38:501 (4,5) - Replace this to 1/2 slider for better following the vocals in song? This will also nerf these huge spacing jumps, since you making this almost the same as for the active snares here 02:53:990 (3,1,2,3,4).

00:04:099 - 00:05:566 - Not really a big issue, but I think that music does not change so much to do such change in SV (1.0x -> 0.7x), since what you follow with 1.0x SV is only snares with drums, but overall intense is not really changed, so it's will be better if you nerf this a bit. Just for example, use the first SV as 0.8x for better representation.

01:37:686 (7) - Remove this circle? There is no sound and making this for a Hard diff might be looks like overmap, which is not really recommended to use. Also, I think this will make some gap in 1/1 that will show better the transition to kiai.

02:32:631 (1,2,3,4,5,6,1) - Since it's the most intense vocals here, I think you can give more spacing for them? Vocals here is like more high-pitched, and would be better if you also show it with more spacing.

02:35:403 (1) - should be Ctrl+G for a consistent spacing usage as 02:35:729 (2,3,4)?

02:43:066 (1,2,1,2,3,4,5) - This chain might be feels pretty complex with using such streams after reverses in 1/4, if you really wanna leave it as now, just make 02:43:392 (2) - this as 1/2 slider and this would be ok. (or you could make 1 time reverse for these 1/4 reverse sliders which would works good too)

02:50:729 - I feel this is kinda awkward way of dropping with gap, I think placing a circle here as you usually do in kiais would fitting more better for rhythms?

01:55:946 - same thing here.

02:53:827 (3,4) - Spacing is extremely huge here with returning-back flow. In the current way a new players probably would have some suffer to hit this, so try to do something like this:

00:35:240 - Maybe you could add here something for highlighting the instrumental and intense part of vocals? It's kinda sad, when you just skipping it, even when other diffs have something here.

something like this works really good

00:49:425 ; 00:52:033 - would like to suggest add here a circle for maintain the vocals, it won't ruin the contrast between section because of 2/1 gap moments here

01:28:718 (1,2,3,4,5,1,2,3,4,5,1) - The rhythm, which consist of only 1/1 gaps looks pretty underwhelming here, even while you show contrast by 0.1x SV change. At least, you may put here 01:29:207 ; 01:31:816 circles on red tick and move this closer with DS which will also 01:30:349 (4) ; 01:32:957 (4) - make this rhythm more enjoyable instead of oversimplifying.

01:43:718 (2) - Maybe replace this slider by a circle to make this chain a bit less of 1/2 rhythm 01:43:718 (2,3,1,2,3,4,5,6,7) - ? I see the rhythm of vocals, but it's also looks a bit overdone, so it will a bit simplify this moment.

02:38:501 (3) - same.

02:20:892 (1,2,3) - small ds issue? must be 1.0x and not 0.87x

02:45:675 (4,5,6,7,1) - This repetitive slider + circle sounds pretty out of the rhythm and I think this one might be fits more better for the vocals:

03:00:022 (1,2,3,4,5) - I feel this rhythm is kinda do not maintain vocals properly, I think the better idea that you did before was 02:55:131 (1,2,3,4). Making it same will be fits better or you could just delete this circle 03:01:164 (4) - which is also working good too.

03:03:609 (1) - Maybe replace this with the circle because vocals starts from 03:03:936? This might be feels much better imo.

03:05:321 (1) - Could you move this spinner to 03:05:403? because currently player might be a bit confused how drastic spinner appears in 1/4.
