01:06:915 (1,2) - i think the click on the red tick is not really necessary, sure there's a sound on the red tick but, seeing as your main focus is on the piano and the vocals, it might be better to just keep a 1/1 slider since both of those instruments are held, applies to all choruses
01:36:423 (5) - might be a good idea to remove the reverse to give players a little break? this section of the song is less intense than the kiai yet you have a really huge chain of 1/2 gaps here, longer than anything in the kiai so it might be a good idea to have a little break here, if you feel it's too empty though you may add a circle at 01:37:161 - for the guitar
03:07:038 (1) - you should move this at least 1/4 beat further, give players some time to react to the spinner
03:17:735 (2,1) - uh sorry to ruin your stacking party but this could EASILY be mistaken as 1/1 when it's actually 1/2, i'm guessing it's not on purpose though
[Hard]
00:17:243 (4) - looks weird to me to have a jump here, especially such a large one in the intro.. if you're planning on keeping it you may want to ctrl+g this slider so you actually have to jump to the 2 kicks at 00:17:735 (1,2) - ?
00:51:915 (2) - again i'd argue this is a pretty harsh jump, it also doesn't help that it's more than twice the size as 00:50:932 (4,1) - when 1 is audibly more intense than 2
03:07:407 (2,3,4,1) - uhhhh not sure if that's a good thing to have in a hard diff, even if the bpm is low keep in mind that this might be hard to read as players would usually expect triples here, not a constant 1/4 stream, might want to reduce the spacing to make it more readable
[Insane]
00:22:653 (4) - i think the overlap with 00:21:669 (1) - looks a lot messier here than what you had at 00:20:194 (2,3) -, feels a bit out of place. also, how about making it the same slider as 00:22:653 (4) - as they cover the same sounds?
00:34:210 (3) - how about making this a 1/4 reverse as the guitar is playing a triple here?
00:55:112 (1,2,3) - this is much easier than the other patterns in the choruses in terms of spacing and flow, maybe you could reverse 2 and 3 to make up for the much lower spacing?
01:10:850 (1,2,3) - this one however plays really awkwardly compared to the others which play at relatively comfortable angles, the small edges at the ends of the sliders are really misleading too
01:36:423 (1) - 5 is covering the repeat arrow, try overlapping instead of stacking them
02:13:800 (1) - why is this not the same slider as 02:14:538 (2,3) - ? they're pretty much following the same thing
neat map, gl!
