Since there is a problem with the "Second Gonkanau", I'm gonna give a small suggestion and things to fix..
Every slider from 01:54:584 to 02:05:493 doesn't end in a correct time, they end before it supposed to, did you removed the correct SV for that part?
Well... Adding a timing point with x1 SV right on 01:54:584 will fix the problem.
02:05:493 (1) - This combo color is entirely different from the rest in the current section.
And some suggestions...
00:43:948 (2) - Hm... This slider already looks good to me, and already fine as it is but just my suggestion to change it (feel free not to since the current one is already fine as it is) like
this pattern to make it consistent with 01:38:220 (3,4,5,6,7) - , and I already know that this slider is there to represent the quietness over there.
02:42:584 (1,2,3,4,5,6,7,8) - Well, personally, I think it is a bit better to move it into 1-1-1-1-2-2-3-4 and what I mean by this is 4 notes stacked each other then move the location with low spacing then 2 stacked note, then another two note without stacking and still a low spacing, I feel like someone mentioned this already but I can't find it, and also 02:48:039 (3,4) - move this from 02:46:948 (1,2) - with a low spacing too.
Good luck on this map though.
