00:42:987 (5) - feels weird to map this vocal with a circle but skip the vocal at 00:43:279 - (I know there's a piano sound there too, but it's really faint). Probably best to make 00:42:255 (4) - a 3/2 repeat slider instead
00:21:182 (3) - your NC patterns are messed up because of that 4 beat interlude at 00:19:133 (1,2) - . 00:21:182 (3) - 00:25:865 - 00:30:548 (4) - 00:35:231 (2) - are the stronger of the alternating downbeats and should be NC'ed instead of 00:23:523 (1) - 00:28:206 (1) - etc...
00:17:084 (3,4) - this one is probably ok since you've introduced the rhythm already, but I think something like this (https://puu.sh/zK08G/998e5392fb.jpg) is still better since noobs get confused by 3/2 rhythms.
00:08:304 (3,4) - polarity issue. It's especially bad here because it's visually spaced as a 1/1 gap. Either extend 00:08:304 (3) - to the red tick at 00:09:036 - or visually space 00:08:304 (3,4) - out more. Something like this: https://puu.sh/zJZZS/b74aedc6af.jpg
01:28:060 (1) - personal preference, but making players spin as fast as possible doesn't really fit with the music fading out calmly. I know some other mapsets have something similar, but I don't think it's good.
01:15:328 (3) - I think 1/2 slider would be better. There's no sustained sound here and there's a sound on the red tick.
I think it's ok since it's only the first slider. Also, because it's wavy, it plays slower than x1.20.
It's the climax of the song, but I will consider changing to 2 reverse sliders if it is mentioned again.
somewhat on purpose, since I want the emphasis to be on 01:08:204 (2) - 01:08:673 (4) - by using larger spacing or awkward flow
basically I want a slider here to represent the vocal the same way as 01:03:048 (2) - and some 1/4 rhythms make kiai more dense
