M4M, I'm garbage at modding higher diffs but I'll try.
General
If you're using a consistenant dashing distance for 1/1 dashes, try 2.3x spacing so the distance is clear that it's a dash. If the dash isn't clear, it may be confused as a walk. Example: 00:00:739 (3,1) -
I can't really say anything for a overall flow of the map but some of your long sliders felt a little slow in the beginning of the map, but I think it won't affect the map's overall quality much unless another modder comments on it.
Specific
00:21:367 (2,3,4) – This flow is a bit weak when the 'te' vocal/strong piano. Put a dash between (2,3) like you did at 00:23:098 (2,3) - for consistency.
01:24:685 (6,1) – Overmap on hypers. There's no strong sound on (2) for there to be a hyper and the vocal is very gentle here. Remove the hyper on (1,2) but keep on (6,1) for the vocal emphasis.
01:43:435 (5,6,7,8) – Make this more into a C-curve. Your hyperdash distance for 01:43:651 (8,9) – should not be larger than the entrance to the kiai at 01:43:723 (9,1) – because it doesn't give the kiai the proper emphasis it deserves.
03:17:281 (1) – This would be better as a single note on 03:17:281 – because the long sound doesnt give enough feedback on 03:20:502 – for it to sound natural. Like, there's no sound there so there's no point to the slider unless you're just trying to avoid a break checkpoint. If anything, the checkpoint works more than the long slider.
04:54:479 – set the spinner volume at 5% at the beginning so it's less distracting.
Good luck.
