01:19:396 (4,5) - what about lowering sv on these to 1.6 and 1.2 respectively would fit with what you've been doing so far, also could increase spacing from 5,1 so there's more impact on the 1
02:59:289 (2) - can start kiai from here instead of 02:59:493 (1)
02:59:289 (2) - finish here instead of 02:59:493 (1) (also can clap instead of whistle if you want)
00:14:737 (1,2,3,1,2,3,1,2,3,4,1,2,3) - i think whistles would work here, following the violin (this applies to other difficulties)
00:38:837 (1,2) - feels underwhelming to have these in the middle, maybe do something like this?
should probably change the background into another one since the fetuses may be a little bit explicit
00:39:079 (4,1) - could move these sliders like this so it flows better and is less awkward to aim
