Hello.
[Easy]
As I can see and hear:
00:04:290 (2) - this is mapped for the same music as this 00:19:290 (2,3) - , but for 00:19:290 (2,3) - you've put whistle here 00:04:290 (2) - and for this 00:19:290 (2,3) - here 00:19:759 (3) - . You should've put whistle here 00:19:759 (3) - instead of 00:19:759 (3) - .
Same here 00:27:259 (3) - . 00:27:259 (3) - istead of 00:27:259 (3) - .
01:34:290 (1) - whistle here. Because here you've put whistle 01:04:290 (1) - .
And I saw few bad blankets like this one 02:51:165 (3,4) - .
[Normal]
01:22:805 (1) - swap with 01:22:571 (5,1) - , this strong beat should be emphasized 01:23:040 - .
And here 01:26:321 (5,1) - . And here 01:30:071 (5,1) - and others.
02:38:977 (3) - I'm not sure with this slider, path isn't this clear as it should be in Normal tbh.
01:34:290 (1) - whistle, ye.
[Hard]
00:31:477 (1) - NC looks random.
02:46:711 (6,7) - 2.17x looks inconsistent here, make 2.3 as before.
03:01:711 (6,7) - and here, yes.
01:34:290 (1) - and whistle, I guess.
Btw, there's no triplets in first kiai, maybe add few?
good luck~
