I'm a sucker for stuff like this.
[Insane]
00:06:950 (2) - This is mapped to something barely audible compared to the slider tail right before. I recommend either deleting it or changing 00:06:388 (1) - to a circle and starting a 1/2 slider on 00:06:763 instead. Unfortunately that doesn't represent the synth or whatever..
00:12:013 (1) - I feel as if it'd make more sense to use a circle on 00:12:200 - instead, for a better lead in to the rhythm you start following. But at the very least, I don't think this was intended to be NC'd.
01:04:888 (1,2,3,4,5,6,7,8) - Seems like this kind of overkill compared to the overall intensity of this section, probably due to the visual spacing compared to 01:07:888 (1,2,3,4,5,6,7,8) for similar sounds. I'd just make the visual spacing more consistent between these (I'd prefer if you kept this pattern though).
01:07:888 (1,2) - Can't say I understand the purpose of this stack, since most of your stacks have been 1/1 and the note under this doesn't seem particularly subdued, nor does 01:08:263 (3) deserve the emphasis that this causes.
03:23:450 (4,5) - Pretty big jump but I can't tell what's supporting it, since there aren't strong drums like there were on 03:23:263 (3,4).
[Harder]
+1 for diffname (though I thought people would call these Light Insanes).
00:04:888 (4) - I suggest shortening this and adding a circle on 00:05:638 given it's strength. An alternative would be changing the entry direction of this repeat to be consistent with 00:10:888 (5) and how the repeat/tail are emphasized.
00:37:513 (2,3) - I'd increase spacing here to be consistent with your emphasis on these sounds, similar to 00:40:513 (3,4).
00:43:513 (2,3) - As above.
02:57:388 (1) - This vocal should start on 02:57:294, but I don't know how you would deal with that 3/4 gap otherwise.
[General Zhao's Hard]
00:24:013 (4) - You could extend this repeat to the blue tick, since there is an audible beat in, and it'd add some more emphasis on 00:24:388 (1). Only mentioning this because of 00:18:013 (4).
02:27:013 (1,2) - It doesn't seem like this broken flow expresses anything in particular, so I'd suggest fixing this by moving 2 in the direction of 1's slider tail.
03:43:700 (3) - Since you didn't map 03:42:950, it would make sense to leave this out despite being stronger, due to the emphasis it puts on the vocals here.
03:58:888 (1,2,3,4,5) - Pretty big diff spike that ignores the vocals you were emphasizing a measure earlier. I suggest changing 03:59:450 (3,4,5) - to a 1/2 repeat.
04:09:856 (1) - There's no individual held sound that warrants this spinner, so I'm not sure why it's here.
[Easy]
00:47:638 (3,1) - I wasn't aware 1/2 gaps were allowed in an Easy.
03:05:638 (3,4,5,6) - This looks pretty confusing to read for newer players due to the even visual spacing here. I'd spread these circles around more.
I looked at the normal too but I couldn't find anything worth mentioning.
Good luck!
