02:31:285 (1,2,3,4,5,1,2,3,4,1,2,3,1,2,3,4,5,1,2,3,4,5,6,7,1,2,3,4,1,2,3,4,1,2,3,4,1,2,3,4,1,2,1,2,3,4,5,1,1,2,3,4,1,2,3,4,1,2,3,1,2,3,4,1,2,3,4,1,2,3,1,1,2,3,4,1,2,3,4,1,2,3,1,2,3,1,1,2,1,1,2,1,2,1) - I really like what you did with the slider velocity here.
03:25:714 (4) - should be 1 repeat longer since it feels strange because we ended the slider before the music ended the sound.
02:27:857 (5) - a circle or slider should be on the spinner end since spinner ends can't convey such an intensive sound. If you follow my suggestion then you should also make the spinner have around 10-20% volume so that we can't really hear the spinner end.
02:25:714 (1) - I think you should also map this like you did here 02:24:000 (1,2,3,4) - . There doesn't seem to be a reason to change the way you map that sound and a slowly increasing spacing could really emphasise the build up.
01:45:214 (5,6) - the spacing here is overkill in my opinion and it's easy to miss read it as a 1/2 jump.
00:52:714 (4) - I understand that you are following the singer but in my opinion it may be better to map the 5 note burst here.
00:20:571 (1,2,3) - you mapped this sound like 3 different ways before. You should be consistent with how you map these sounds in my opinion.
Also the spacing is pretty much overkill. A bit later in the song you map the same sound using a way smaller spacing so if you want to keep this as 3 circles then you should at least use the same spacing as here 00:27:428 (1,2,3) - and use a consistent rhythm for the sound.
00:16:714 (7,8,1) - you should nerf the spacing here because it's still the beginning so it shouldn't really have such a big spacing. 00:15:000 (3,4) - this is fine since they are sliders so you have a bit more time to aim it.
00:10:285 (1,2) - you should map it like you did before and after this part. Like this 00:03:428 (1) - .
I would also overlap 00:37:744 (3) - with 00:37:594 (2) - to give more emphasis to the loud drum sound that plays on 4.
Same here 00:28:294 (1,2) - .
In my opinion he can also just delete 00:07:594 (1) - to follow the singer more like he did most of the time before.
01:55:785 (5) - same here. A single slider is way underkill since that part of the song is supposed to be a harder part of the music.
