00:15:066 (1,2,3,1,2) - i highly recommend to avoid rhythm what you used here cuz its not following downbeats, snares or anything imo?? so just use 1/2 rhythms is much better, also pls avoid to emphasis finish by slider tail on 00:16:414 -
00:15:403 (2) - think it makes more sense to be 1/2 slider or two notes to make the sound 00:15:740 (1,2) - stands out more
00:26:526 (3,4,5,6) - heres kinda uhhh calm part you know but the usage of rhythm here is not following the music itself ig so what about changing 00:26:864 (5,6) - to 1/2 slider or nerf something
00:29:897 (6,1) - idk you havent used this break before so could u give it a try to add note 00:29:897 - , 1/1 slider on 00:30:066 - ?
00:52:819 (1,2,3) - this is surprisingly hard to notice 00:53:830 (1) - and can be confusing. since hard is suitable for new players, i recommend placing them in a straight line rather than a circle to make them easier to see intuitively
01:45:571 - fill the rhythm and 01:45:740 (2,3) - ctrl g the rhythm is better to follow cuz point 01:46:077 - by slider tail is way too awkward
03:03:605 (1,2,1) - spacing here is not really ok for 1/4 tbh, as it looks like 1/2 not 1/4. personally I would stack the first two and make the second reverse end at red tick so that you can maintain the current pattern & spacing for the triple
also, 03:05:122 (3,1) - visually unequaled spacing would be very likely to mislead the new players to see the gap to be longer than 1/2. stuff like this would be much more predictable for new players (you might need to adjust 03:05:628 (1,2,3) - to avoid potential overlapping)
