Alright let's see what I can find.
General:CLEAR!
Normal:00:18:730 (7) - a NC here because it follows the guitar
00:22:126 (2,3,4) - replace this for a 1/2 slider to make it easier?
00:24:390 (2,3) - replace this for a 1/2 slider? same reason as above.
00:39:532 - remove the break here. the hp bar doesn't decrease that much and it's unnecessary IMO
00:48:164 (1,2,3,4,5) - to make it easier, replace all this for a 1/1 repeat slider.
00:50:428 (3) - NC here because of new vocals?
01:02:032 (2) - make this a 1/2 repeat slider to make it easier and replace the whistle for a clap at the repeat arrow to keep the consistency.
01:06:277 (5) - hmm IMO this looks boring because of the number of repeats. instead make this repeat once and replace the 3rd repeat and the end for another 1/1 slider. IMO this looks fun for players.
01:32:315 (1,2) - silence the slider's end. it's too loud and it doesn't go in sync with the vocals. suggest that you add whistles at the end of (1,2). it sounds empty with no hitsound.
01:40:240 (1,2,3,4,5) - replace this for a v-shape slider to make it easier? like
this02:02:881 (3) - add a finish here and reduce the volume from 65% to 45%. I feel that there should be a hitsound on (3) since it's at the downbeat.
02:37:975 (3) - maybe face this horizontally or stack this on (2) because the end is touching the hp bar. since it's near the end and this is the easiest diff, beginners might mess up because of that.
02:40:523 (4) - i think about forgot to add a clap at the end. it should be there to keep the consistency.
02:45:900 (5) - same as 00:50:428
if you follow the majority of these suggestions, the star rating should reach 2.98
Hard:00:13:353 (5,1) - spacing error. follow the DS because IMO it looks bad during gameplay.
00:22:692 (5) - i think you forgot to add a clap at the beginning of (5). add it to keep the consistency.
00:27:504 (5,6) - instead of the whistle being at (6), move it to (5). it sounds weird if it's at (6)
00:39:590 - same as 00:39:590 on normal
01:10:947 - add a spinner and end it till 01:13:070 to follow the long pause in the vocals.
This is the best i can do. GL
