The concepts in the kiai need a little bit of introduction. What I mean by that is just during the calm sections you can introduce some of the patterns (with less spacing of course) that you use in the kiai.
I think mixing the snap aim and flow aim in the kiais is a great choice and it adds variety but a few patterns are a little sudden. (Note also that you can use these patterns without introducing them but I think it would improve quality to show some sort of progression of the ideas).
02:10:288 (1,2,3,4,1) - is one of the most sudden examples I can think of, 130 bpm 1/4 jumps are fine but this overlapped pattern is very different from standard flow aim or standard snap aim. My suggestion to introduce it is just to modify a section you already have in the map. 00:18:596 (1,2,3,4,1) - is what I am thinking of. If you can adjust this pattern here to be closer to the kind of hard overlap snap pattern then it would work as the small introduction. Something similar to this would do a good job of introducing the pattern early: https://osu.ppy.sh/ss/13283848
Personal opinion that I am not even too sure about, but you can introduce some snappier aim ideas in the opening or somewhere else as you please. 01:42:596 (1,2,3) - This would be a good spot to get a little snappier with the movement.
01:46:288 (1,2,3) - This is a little bit of what I am talking about, and I approve of this specific pattern to introduce the kiai concepts. Idk if you want more or less introduction, it is up to you.
You seem to get all your feedback through ingame chat so I guess I'll be the first to give some through here :d
During the drops (01:58:635 / 04:11:788 / etc.) the distance snap on the streams are both too high and too low.
Currently it's .85 and 1.75 ds at 1.00x SV; I think it'd be much better if you used 1.00 and 1.5 instead.
Also, the spaced streams aren't really supported by the song, so I'd suggest putting a little more of the higher distance snap through the rest of it so they feel less awkward and out of place.
