[Easy]
00:09:984 (4,1) - Consider trying to move note placements here, since you don't want to move 4, you can move 1 to look more visually appealing. NC-ing 4 is also an option but it would still look somewhat awkward (you would have to remove the NC at 00:10:376 - if you wanted to NC 4 though)
00:22:925 (1,2) - Small detail, you could make these the same shape (copy paste 1 and reflect it) so that way it's nice an symmetrical
00:35:474 (1) - Maybe use soft finish here? The drum finish doesn't exactly capture the intensity of the transition between the somewhat fast part to the slow part
01:04:886 (4,1,2,3,4) - Maybe try something like in the box below. Currently when the vocals say "mawaru" it doesn't feel very distinct from the previous measure. This would also apply to the second time this verse comes up.
01:27:239 (3) - Would be better to end at 01:28:611 - in my opinion, that's when the vocals end and I can't really hear anything distinctive after that point
[Normal]
00:00:180 (1,2,1) - For here I would try a rhythm like below. Considering that you use quite a lot of 1/2 in the Hard diff it can also serve to balance out the set as a whole. Making 2 circles instead of the slider help further accentuate the drums on those beats.
00:09:984 (5,1) - I still suggest NCing 5 instead of 1 though, the follow points make for an awkward transition
00:22:925 - This section (from this inherited section to the start of the next) feels a lot more dense than the section before it. You may want to balance out the diff a bit by making the section before a little more dense
01:27:239 (1) - Same thing with the ending as the Easy diff
[Hard]
00:21:356 (1,2,3) - I feel that this should have a little bit of a jump to it, it's the transition from a vocal section to another vocal section with heavy emphasis on the downbeat, it deserves a little bit more than the usual spacing that you have
00:22:141 (6) - If possible, try to find a way to make 00:22:337 - clickable. The beat is pretty strong and it feels weird that it only lands on a slider end
01:27:239 (1) - same
[Insane]
00:21:356 (1,2) - Make sure you hitsound the slider end of 1 and 2 with a normal sampleset, this goes for other diffs as well
00:29:003 (6) - Could put drum clap here
00:35:474 (1) - This is kinda just a thing for all diffs that I only am going to point out on this diff and the easy lol, soft finish works better here because drum finish doesn't exactly capture the intensity of the transition
01:02:925 (3) - 01:04:101 (2,3) - Are you sure you don't mean soft whistle? You only use drum whistle here?
01:27:239 (1) - Slider end thing
That's about it, the hard was pretty nice. Make sure you go over your hitsounds again though, there are a few inconsistencies and a few things you could add to make it much more enjoyable to hear~
