Alright let's see what i can find.
General:The preview time is inconsistent. like Frostmourne said set it to 58120 like the other diffs.
add "ending" in the tags since this is the ending in the anime.
the offset should be at 684. well that's where the big white tick is. i'm no timing expert but start it there. i feel that there should be notes there because there's so many opportunities where you can add notes.
Easy:00:15:057 (3) - this wave slider can look a lot smoother.
00:40:185 (4) - unstack this because beginners might hit this too early or late.
00:45:826 (1,2) - spacing error. it's at 0.93. instead try to make the slider like
this or something close to this as it not only follow the spacing, but it blankets the next slider.
01:23:262 (2) - just make this a curved slider. i don't like the turn at the end because it looks ugly.
02:07:877 (1) - this wave slider can look nicer.
02:34:031 (2) - make this a 1/2 slider with a repeat. it follow vocals accurately. if you ignore this then make this a 1/2 slider like at 02:36:082.
02:36:082 (2) - ^. if you ignore this leave it as it is.
03:11:467 (3) - same as 00:40:185.
03:23:774 (4) - ^
Normal:00:30:941 (3) - remove this and start at 00:30:813. add a slider and end it till 00:31:197. it follows vocals accurately.
01:00:684 (3,4) - replace this for a 1/1 slider as it follows vocals nicely.
01:09:402 (3,4) - ^
01:32:736 (6) - delete this note. you're following vocals not the instrumental.
01:34:018 (2,3) - delete these 2 notes and do this: add a slider and end it till 01:34:402. add a repeat as well as it follows vocals accurately.
01:42:223 (3,4) - same as 01:00:684
01:50:428 (3,4) - ^
01:58:633 (3,4) - ^
02:06:838 (3,4) - ^
02:31:710 - add a circle to follow the drum?
02:51:966 (3,4) - same as 01:00:684
03:00:172 (3,4) - ^
03:08:377 (3,4) - ^
03:16:582 (3,4) - ^
03:24:787 (3,4) - ^
03:32:992 (3,4) - ^
what really puzzled me is the clap hitsounds during kiai time. they don't sound right if it's at the red ticks. it'd sound better if it was at the white ticks.
Hard:00:19:402 (6) - IMO this looks boring. instead make this repeat once and add another 1/4 slider to replace the last repeat and the end.
00:23:505 - add a 1/2 slider and delete (2) to follow vocals.
00:24:531 - same a above but delete (4)
01:29:146 (1,2) - you can replace this for a 1/2 slider with a repeat, replace (1) for a 1/2 slider and leave (2), or replace these both for a 1/1 slider. it follows vocals accurately.
01:40:941 (2) - make this a proper curved slider. it looks ugly like that.
01:49:915 (7) - delete this note because there's no vocals here.
01:58:248 - add a circle to follow vocals?
02:05:813 (4,5) - replace this for a slider as it follows the pause.
02:40:901 - same as 01:58:248
03:16:069 (7) - same as 01:49:915
03:27:479 - same as 01:58:248
03:32:479 (7) - same as 01:19:915
IMO this needs work on the notes. there's so many opportunities where you can add notes mainly because of the vocals and instrumental if you listen carefully, and again with the claps.
This is the best i can do. GL
