00:17:078 (1,2) - 00:22:891 (4,5,6) - Inconsistent rhythm usage which is pretty clear. Would recommend having 1/4 sliders on 00:23:078 - and 00:23:453 - since you do not normally represent the sounds that you do at this point with the reverse slider when there are more interesting things happening.
Additionally to combat 1/2 slider spam maybe you could have hitcircles on these places 00:22:516 - 00:22:891 - or a 1/1 slider over those two points?
00:28:766 - maybe u can make same spacing with 00:28:891 (2,3) - to make 1/6 rhythm more notable.
u seem to use many stacks on the 1/4 rhythms, it makes the rhythm a bit hard to read.
00:31:391 (1,2) - 00:50:891 (1,2) - 00:52:016 (5,6) - 00:52:766 (7,8) - 00:54:641 (3,4) - 01:26:891 (1) -
maybe kiai is fine, cuz the rhythm is very obvious.
00:37:016 (2,3,4,5) - This is just unacceptably hard to read at this difficulty level. Since introducing a way to have 1/6 and 1/4 rhythm at the same time in a hard would be a pain in current circumstances, I'd recommend moving the 2 to here 00:36:953 - and keeping the pattern the same. Would follow the drum beat still
00:40:516 (4) - i think u need to move it away and keep the similar spacing with 1/4 spacing.
this one is almost 1/6 sapcing like u do on 00:28:891 (2,3) -, it would make players misread the rhythm
00:41:078 since you followed the vocals so far it would make sense to map this one too
You could reduce 00:40:703 (5) - on the previous bluetick & put a circle on 00:41:266
00:50:891 (1,2,3,4,5,6,7,8,9) - overall this part's rhythm is far more dense than the rest of the section and feels unbalanced. I suggest simply making 00:52:141 (6,7) - into one long slider (1/2) to reduce that density
01:03:641 (4,5) - this is the only 1/4 double that is spaced in the kiai so it feels really out of place of your overall structure. I suggest you stack these or change some other doubles to be spaced.
01:11:266 (3,4) - i think that there is weak beat expression there, and the strong beat on the end of 3 should be a circle rather then a slider end, something like this, would be better imo https://osu.ppy.sh/ss/16045212/dc90
01:21:766 (1,2,3,4) - u could decrease the spacing a bit to show it's 1/3 rhythm since u use similar spacing on 01:18:766 (1,2) -
