00:03:322 (1,1,1,1,1,1,1,1,1) - could unoverlap the 1/3 stream to recognize them at first glance and create a bigger difference, ranther than just an nc spam, between them and the 1/4 stream 00:04:306 (1,2,3,4,1,2,3,4,1,2,3,4,1) -
00:09:388 (6,7,8) - (synth) since you already have a triple for a different instrument (drum) at 00:09:060 (3,4,5) - you could change 00:09:388 (6) - into a 1/4 reverse slider to mark this variation
00:41:847 (2,3,4,5,6) - the spacing is too high in relation relation to the musical intensity of the part...
you can compare it to 01:05:781 (4,5,6) - for example, you got a bigger spacing in the first case (slow part) than the jump in your kiai, which doesn't make sense in the difficulty progression
00:45:290 (1,2) - since you never used 3/4 slider in the slow part, this one feels out of place and not consistent
what about extending it to a 1/1 like 00:41:355 (1) - ? it seems to be a better alternative
00:53:814 (3,4) - maybe you can reduce to exaggerate the fact that it's a very very low intensity section? -> https://i.imgur.com/WnE0N3D.png
