shouldn't the kiai times start at 02:14:710 and 04:02:296 instead? The sections just before these timestamps are weak sections of the song used to emphasise the upcoming chorus, and I believe you should only be using kiai time on only one section (the strong section), not both.
I also think the preview point should be 02:14:193, but that doesn't bother me. I didn't recognise the song because you had it previewed at such a weird part, though.
also a lot of subjective modding coming:
00:07:533 (3) - I see that you ended the slider on another flute beat, but the spacing to the next slider is awkward since the spacing is 1/2. Personally I'd make the slider repeat to remove that awkward pause, as well as making the spacing similar
00:09:983 (1) - any reason why you chose not to sustain the flute to 1/4 like the others?
00:10:508 (3) - slider end should be 1/4 shorter
00:13:814 (2) - remove this, completely unnecessary
00:15:624 (5) - ^
00:22:534 (3) - either move this closer to the slider, or move the upcoming sliders a bit further. This 1/4 spacing is way too similar to the 1/2 spacing of the upcoming sliders.
00:31:542 (2) - would play a lot better and flow better if it were stacked onto the next slider imo
00:31:930 (4) - ^
00:42:894 (12) - way too much spacing for a 1/4
00:51:415 (1,2,3,4) - why is this spaced much more than 00:55:563 (1,2,3,4)
01:03:839 (9) - NC?
01:06:046 (9) - NC should start here
01:06:434 (1) - change this to 1/2 slider, random 1/1s are very awkward to play if you do it in the middle of a section
01:18:330 (4) - you could do something with this, maybe a 1/8 or 1/6 repeat slider
01:18:460 (5,6,7,8,9,10) - this stream doesn't really fit the music, I'd do kick sliders instead to emphasise the heavy beats
01:24:538 (4,5,6,7,8,9,10,11,1) - this plays to nothing, and you missed a very good opportunity to put some nice jumps to emphasise the beats!
01:28:482 (3) - remove this, plays to nothing
01:42:124 (1,2,3,4,5) - I assume you were following the vocals on the previous part before, so why the sudden change?
01:44:193 (4) - as said before, the 1/4 spacing is very similar to the upcoming 1/2 spacing
01:44:710 (7,10) - ^, you could also add NC to these repeating patterns
01:59:969 (4,5,6,7,1) - why is this a stream? If you're going to add a stream on sustained notes, then the stream should be connected to the slider before it
02:00:357 (2) - ctrl + g for better flow, back and forth patterns with sliders are terrible to play and plus this is the only section where you did it like this for some reason
02:00:745 (4) - ^
02:01:132 (6) - ^
02:01:520 (8) - ^ and also understates the huge spacing spike from 02:01:779 (1) onward
02:04:236 (4) - the vocal actually starts on the blue tick
02:05:270 (4) - ^
02:07:985 (2) - if you're emphasising vocals, the NC should start here instead
02:09:408 (4) - the vocal actually starts on the blue tick
02:11:219 (4,5) - these beats should be moved on the blue tick to the right. Also take this chance to do something creative with it
02:12:253 (4,5,6) - this sounds really weird? could be same as ^
02:27:512 - add 1/2 circle there is a beat there
02:28:546 - ^
02:29:581 - ^
02:30:615 - ^
02:53:632 (5) - remove this, it looks like you're strictly following vocals so this is completely unnecessary
03:06:046 (5,6,7,8,9,10) - like 01:18:460 (5,6,7,8,9,10) if you're going to put streams on sustained beats, then start the stream on the sustained beat.
03:09:408 (1,2,3) - very very very very very hard to read patterns like this, please change it or add some sort of indication emphasising the 1/1 going to 1/2.
03:11:477 (1,2,3) - ^
03:13:546 (1,2,3) - ^
03:32:684 (2,3,4,5) - ^
04:14:710 (1,2,3,4,5,6,7,1,2,3,4,5,6,7,1,2,3,4,5,6,7,1,2,3,4,5,6,7) - what I said about the previous kiai, you're missing some 1/2 beats between some of the quin streams
04:20:917 (1) - looks like you wanted to avoid mapping the rest of that section tbh. Shorten this spinner so that you can map the beats that come after it, or better yet just use a slider for 04:20:788 (4) and map 04:21:693
04:26:219 (1,2,3,4,5,6,7) - streams sound very offputting if you silent-hitsound every second note. Please don't
04:26:606 (7) - I think this should be a slider to emphasise the sustaining vocal, because the instrument is still playing. 04:27:124 (8) is very appropriate though
04:27:641 (1) - I think you should map the two 1/2s that come before it, to give emphasis to the upcoming kiai
04:27:641 (1) - this would sound better with a 1/2 slider instead, or at least another 1/2 note coming after it
04:39:926 (6,6,6,6) - wtf now you start mapping that 1/2 lol
04:46:522 (1) - I'd map the vocals as sliders, spinners should only be used for very long sustained notes
