00:02:272 (3) - it'd be nice if you did something like 00:03:875 (6,7) - and mapping kat to that repeating rise in pitch that keeps coming up. Same with 00:03:188 (5) - 00:05:936 (14) - 00:06:852 (16) - 00:09:600 (25) - etc
00:04:447 (8) - move it from 00:04:447 to 00:04:333 for conciding the rhythm of the synth
00:07:768 (18,19,20,21) - having 4 kats in a row quite randomly for no reason feels really weird, similar things with dons at 00:12:577 (38,39,40,41) - . There are changes in pitch so you should vary colours too. Only do this for when the pitch doesn't change I think
00:18:646 (68,69) - it's more readable if you have a colour change when changing sv so greatly. I'd do something like d k k d kddd
00:18:646 (68,69) - imo this doesn't work. That extra sound is at 00:19:733 - not some 1/12 after an already late note. I'd suggest doing a 1/8 doublet like this https://osu.ppy.sh/ss/18754237/e0ac . Doing this also lets you map 00:19:905 - which is a pretty bad sound to miss
This goes for all the other doubles too that are like this
00:29:294 (157,158,159,160,161,162,163,164,165,166,167) - this is great more stuff like this please
00:31:585 - this section is missing a bunch of notes mapped to vocals, I understand it's an easier section but it's really weird. Also you randomly decide to map vocals like 00:40:516 (200,201) - which you didn't do before (do more like this). Map 00:41:546 - 00:32:844 - etc
I'd actually just say remap this bit cause evening the backing is on the red ticks, which you ignore. So map: Vocals > Offbeat backing > Weird random bass and drum stuff
00:55:516 - you can do the same thing as 00:48:188 (25) - . And why doesn't 00:47:959 - have a note when 00:55:287 - does?
01:01:127 (312,313,314,315,316,317,318,319,320,321,322,323,324,325,326,327,328,329) - move 313, 321 and 328 to:
01:02:653 (104) - 01:03:569 (111) - 01:04:485 (117) - etc there is no 1/6 here at all it's all straight 1/4 please make this 1/4
Even if it's some goofy concept that I don't get it's used way too often and just feels random. If you decide to not change them to 1/4 (please do tho) only keep the most impactful ones
01:06:394 (346,347,348,349,350,351,352,353) - move 349 and 352 to:
01:59:294 (680,681,682,683,684,685,686,687) - move 684 from 01:59:905 to 01:59:867
02:01:127 (691,692,693,694,695,696,697,698,699,700) - move 692 and 699 to:
02:05:020 (717,718,719,720,721,722,723,724,725) - move 720 and 724 to:
02:08:226 (739,740,741,742,743,744,745,746,747,748) - move 742 and 747 to:
02:16:012 (586,587,588,589,590,591,592,593,594) - ojioidsaopd 5 dons in a row is gross and really hard to read (this is 5* btw). Either make 02:16:394 (591) - a don or 02:16:317 (590) - a kat
02:24:256 (648,649,650,651,652,653,654,655,656,657) - please don't use 1/5 unless there is actual sound for it. That's the only reason it's a thing you can do. For things like this stick to 1/6 or 1/4. It's also super random and unobvious
02:31:814 (709,710,711,712,713,714) - pretty hard to read. Make 02:32:043 (712) - a don, or make 02:31:966 (711) - a don. I think 02:32:043 (712) - would be better
02:52:653 (827,828,829,830,831,832,833,834,835,836,837,838,839,840,841,842,843) - yeah it's mapped correctly but it's super boring. There some 1/4 in the guitar towards the beginning you can choose to map. Also you can also just change the patterning a bit too. Stuff like kkdd instead of kdkd could look nice
02:56:317 (843,844,845,846,847,848,849,850,851,852,853,854,855,856,857,858,859,860,861,862,863,864,865,866,867,868,869,870,871) - same here too kinda, make some fun streams :D
03:17:157 (997,998,999,1000,1001) - is this the first time you used 1/8 like this in the map? If you do keep this I'd remove the 1/6 at 03:16:241 (988,989,990,991) - so that players can at least play it on their main hand
