[LR's Inverse thing]
Well, at first glance, honestly, this feels like an experimental chart or something, it doesn't really feel fitting to the music imo
owell, imma try to mod it anyways
00:10:156 (10156|0,10156|6,10156|4,10156|2,10487|1,10487|5,10487|3) - Feels like you can do some staccato here, shorten these LNs by 1/2 or 3/4
00:27:559 (27559|3,27890|4,28222|2,28388|5,28553|1) - The build up of the LNs here just doesn't feel right with respect to the music, the music enters the 00:27:559 - Timing point here with a strong impact while this pattern is building up, it just doesnt' feel fit imo, maybe you can just throw in the inverse straight away like this

00:45:128 (45128|0,45128|6,45791|0,45791|6) - The impact on these are just not strong at all with these LNs in the way, i suggest an LN shield like this if you insist on keeping this chart LN dense |

01:00:542 (60542|2,60542|4,60874|1,60874|5) - same thing here i recommend a LN shield for impacts, somewhat like this

01:24:575 - You probably get the idea

00:03:691 - Might want to kiai fountain here the music allows it and it feels nice imo, kicking start the chart with fountains are kewl
[Usagi's HD]
00:07:006 (7006|1,7172|0) - idk what's with this not hammering like the previous notes
00:13:802 (13802|5,13802|1,13968|3) - Well idk, this feels inconsistent also in terms of how the idea of using LNs for the guitar is executed here | I suggest this instead

00:30:874 (30874|4,31039|2) - I don't get the inconsistency with the hammers with respect to the previous patterns wfwefniwungfwe
01:24:410 (84410|1,84410|5) - Move to the far left and right sides, it feels better imo when playing
01:23:581 (83581|5,83747|6) - Swap columns for these two, same purpose as ^
[Etlie's NM]
So you probably got your diff name pattern wrong just saying
Etlie's Mania NM -> Etlie's NM Mania
turns out it's genocide being a dumb, please fix it anyways
00:13:802 (13802|2,13968|4) - Might want to ctrl+H for PR
00:59:051 (59051|4) - Might want to remove 1 of them, there's not really anything strong here
01:08:995 - Maybe add a note here for vocals?
01:11:979 - 01:12:476 - Well, if you want to make it slightly harder you can always add on these 2 timing points for vocals/drum
01:25:736 (85736|3) - Might want to shorten by 1/2 so that it ends exactly at where the idk what high pitched instrument starts
[EZ]
00:27:393 (27393|1) - Might want to move to the right by 1, the index finger feels stronger imo ( well for a certain mania play style this will apply )
00:36:841 (36841|5,37172|1) - This doesn't really feel fit to the music at all, might want to reconsider this 1/1 pattern here, it might feel that you are just overlapping a constant 1/1 pattern over these stuff
01:04:686 (64686|6,65680|0,66012|0) - doesn't really feel fit to the music here might want to consider this |

01:14:962 - Maybe add a note here? to mark the end of the LN
01:17:448 (77448|6) - Might want to move to the left hand here so that the impact is even on both hands
01:19:769 (79769|6,80100|6) - Since you hammered these, you should hammer these 01:22:421 (82421|2,82752|0) - for consistency
01:24:244 - Feels like a missing note based on your idea of the patterning here
01:25:736 (85736|6) - Might want to shorten by 1/2 so that it ends on the instrument's start there
