alright lets see
[General]
a few recommendations for the sb:
02:09:590 and 04:01:274: instead of just displaying "Sweet Vanilla", how about "Beatmap By: Sweet Vanilla"? Helps to make it more obvious and distinguish from the title.
04:01:274 - the title display here doesnt have the author "sleepless", was that intentional?
[Easy]
01:51:769 (2) - might want to flatten this a bit to fix the blanket with 01:50:580 (1)
02:42:858 (1,2) - try to position this so 02:44:046 (2) lands right on where 02:41:670 (4) ended
02:51:174 (1) - remove NC here and add one to 02:52:363 (3); then take it off 02:52:957 (1) and you get the correct NC pattern
03:15:828 (1) - feels more natural if you start this spinner at 03:16:125 to follow the piano
[Normal]
00:42:858 (1) - whistle on start?
01:24:145 (3) - have the red dot at the first slider tick, so the slider turns when the vocals change pitch at 01:24:739:
01:30:976 (2) - meant to use a clap here?
02:28:006 (1) - forgot clap
02:54:739 (5) - NC here, combo is a bit long
03:44:937 (2) - clap on repeat
04:28:155 (2) - whistle on repeat? you have it on earlier repeat sliders
[Hard]
01:59:788 (2,3) - try to blanket 01:59:491 (1) here
02:45:828 (1) - forgot a clap on start
02:47:016 (3,1) - these two are a bit far apart which makes it a spot for easy slider breaking, i would increase the distance between 02:45:828 (1,2,3) to solve this:
03:16:719 (7,8,9) - maybe because i played too many insanes, but when i first saw this i read them as 1/4 apart; to prevent confusions like that, increasing the spacing here a bit actually makes it easier to read imo
[Insane]
00:42:264 (2,3) - try swapping for a rhythm like this:
02:13:452 (5,6) - this actually should have the largest spacing according to the music, see if you can reposition 02:12:264 (1,2,3,4,5) to achieve this
02:14:343 (1,2,1,2,1,2,1,2) - i think comboing like this will make this part much easier to read (basically each stack is its own colour, 02:16:422 (2) goes with 02:17:016 (1,2,3)):
02:37:363 (2,3) - a bit easy to misread this due to shorter spacing, you can try something like this:
02:58:303 (1) - unnecessary NC, if you want to keep this add NC onto 03:00:679 (4) for consistency
03:19:986 (4,5) - not stacked properly, it alters stack leniency a bit during gameplay so might want to fix it
04:20:283 (1) - use default whistles in this section like the other diffs?
Well thats all from me, let me know when you are done
