ok I'm the fifth, Let's do something needed
Gerneral
fine 0.0
Hard
00:06:365 (4) - replace the whistle at its beginning and mid with clap, leave the whistle at end, may apply a better sound effect as I suppose
00:12:965 (8,9) - I suggest to use a lower volume for all similar tripples like this and 00:18:965 (7,8,10,11) - and so on, 80% would be nice
00:15:165 (6,7) - may try to switch their order, set a circle at 00:15:165 - and start a slider at 00:15:365 - that would match with the bgm better, like what you've done with 00:14:565 (5) - though I think may wanna keep it for the symmetry
00:34:765 (3,4,5,6) - may try to change their whistle into clap, or only change 4 5 6
00:35:165 (7,8,9,10) - if I were you I would replace these with a 1/4 reverse and that may fit this diff better, a stream of nine with 150BPM seems a bit too hard for this diff. If this appears at the strongest part of the song it may feel better, however it doesn't.
00:47:165 (5) - a clap would fit its end much better
01:00:965 (5) - why is that I think a finish would be much better for this, maybe you may add all hitsounds for this circle `w` also for the next kiai
01:27:565 (7) - may also add whistle to it, hmm I think many of similar notes, at downbeat, with finish, could also have a whistle to emphasize, such as 01:44:365 (1) -
01:29:565 (4) - suggest to replace the clap on head with whistle to fit with the kick in the music
01:45:965 (10,1) - exchange NC may work better
01:59:565 (4) - as I hear almost the same sound at 01:59:965 - , 02:00:365 - and 01:59:165 - , so I would suggest to remove the both whistles at 01:59:565 (4) - 's mid and end. too frequent drum kick(whistle) at this soft part sounds real weird imo, coherent whistles are better be used at intense part as I suppose
02:01:565 (1) - ^ also the whistle on its head
02:02:765 (3) - ^ remove the one at its end
02:10:565 (3) - on the contrary, according the music, add a whistle on its head may be nice, it's intense here
02:39:965 (4) - same as 01:29:565 -
02:54:165 (8) - may try clap clap whistle
02:54:865 (1) - more green lines to gradually decrease volume would be better. of course for Normal as well
Normal
00:35:565 (5,1) - why not exchange NC
00:46:765 (3) - may try move it to 00:46:565 - and add finish for it, I think that would form a better rhythm, and that won't be too hard as you've already have 00:32:765 (1,2) - .same for 01:57:165 (3) -
01:28:765 (2) - same as that in Hard, better replace the clap at its end with whistle, also for the one at the second kiai's end
01:29:965 (3) - missed important finish
01:52:365 (4,1) - better exchange NC as the downbeat lands on 4?
01:00:965 - and 02:11:365 - same as that in Hard
02:51:565 (5) - may add NC here and remove that at 02:53:165 (1) -
not many important points I've found, but hope that somehow helps
Good luck~
