[General]
Inconsistent countdown values.
[Normal]
General issue I have here is that this is the lowest diff of your mapset and you're using stacking for three different distances. 00:00:552 (1,2) - is an outlier in that it is the only stack for a 3/2 gap, but starting at 00:40:376 - you switch from using stacks for 2/1 to using stacks for 1/1, which I think will be hard for your target audience to handle. Make a choice on whether or not to stack for 1/1 or 2/1 and stick with it throughout the entire map - personally I recommend sticking with 1/1 but its up to you.
00:18:622 (1,2) - 00:55:113 (1,2) - Not a fan of how unintuitive this placement is, since players at this level either don't know how to use slider leniency or will click 2 way earlier than necessary as a result of this. You'll likely have to rearrange a bit, but your best bet to fix this is moving 2 farther to the right.
00:21:429 (1,2) - Stacking objects under slider ends is inappropriate at this difficulty level, stick to distance snap for these instead.
[Hard]
01:24:938 (2) - I think using a circle + 1/1 slider would form a bigger contrast with the reverse at 01:25:991 (1) -.
[Insane]
00:03:359 (1,3) - Could add soft-hitwhistles here to match what you did in the intro.
00:18:622 (1) - I recommend using a normal-hitfinish on the head instead of soft-hitwhistle to match 00:29:850 (1) -.
00:36:692 (5,7) - Try adding a drum-hitfinish to the tail of 5 and head of 7 to make this section feel less empty and have these measures pair more nicely with 00:29:850 -.
00:39:324 (5) - I think a drum-hitfinish works better than a soft-whistle, since it sounds pretty weird for your heavy handed drum pattern at 00:38:271 (1,2,3,4) - to end on a lower feedback sound.
00:42:131 (5) - 00:44:938 (5) - Other two diffs had an NCing idea here to seperate the paired guitars, so I recommend doing that here as well or removing it from your other difficulties.
00:45:991 (10,11) - Would be nice to decrease spacing here to follow your idea from 00:43:184 (10,11,12,13) -.
00:48:096 (5) - Swap soft-hitwhistle with drum-hitfinish to complement 00:48:271 (6) - more appropriately.
00:50:201 (3) - Recommend a soft hitwhistle here for the vocal and to pair with 00:50:026 (2) -.
00:51:078 (6) - Try swapping the soft-hitwhistle for a drum-hitfinish to complement the snares on 00:50:903 (5,7) -.
01:00:026 (3,4) - Add drum-hitfinish to 3 and the head of 4 to match 01:00:376 - more appropriately.
01:00:727 - This entire kiai quarter could use more drum-hitfinish usage to pair with 01:11:955 - more appropriately.
Hitsounds apply to all diffs, make sure to copy them properly.
