Your map got bubbled right when I was about to mod this, since I already look through the map and I didn't see anything wrong with it, I'll send a pm with the mod instead so consider them when bubble get pop. I'm late because something unexpected happened yesterday.
Everything is suggestion, but first reply.
SPOILER00:20:847 - [All Diffs] Then I hope you put a whistle here atleast, for some diffs (the easier diffs), it sound a bit too loud for me so you may want to lower volume a bit for those diffs.
01:19:051 (2) - [Normal] Then I think you should put whistle at begin, the piano/bell sound is masked by the snare drum, but I can still hear it.
01:22:104 (2,1,3) - [Hard & Insane] You can always do 30% / 20% volume etc. for the finish if you feel it's too loud. I think it give a nicer effect for the ending than the whistle and I feel it fit really well with the guitar + drum combo. Well this is my perception, but "end your diff with an impact?"

General]
-Won't be checking the custom finish placement for inconsistency since I silenced it to mod the whistle hitsound better.
-Since hp 7 for Insane, -1 hp to all other diff so it's 1 hp > 3 hp > 5hp > 7hp? And since we're talking about difficulty settings here, I would do od 8, your diff has really good flow and I think od 8 would give more of a challenge. I assume you did this since you have doubt about timing, but I still manage to keep 98%+ accuracy at od8 even with my low accuracy.

00:10:428 (2) - Following piano right? (whistle) Why no whistle at repeat? Well checked Hard & Insane and you didn't put it there either, but there was no whistle at where the begin and end are so hitsound pattern is already different from those two diffs. The place where I can hear the piano at 100% speed is on the repeat and the red tick before and after (where you put the whistle in Hard & Insane) so I think you should have one at repeat. Consider removing from begin & end, but I guess I can see why you want to put them there. Main reason why I'm suggesting this is that every whistle follow piano sound except here and don't forget it applies to Normal too.
00:42:763 (2) - Hmm, why whistle at begin? Don't hear the piano here and vocal plays 1/2 earlier. Applies to Normal as well.

Normal]
00:28:392 (3) - No whistle at begin here like the other diffs? Seem off that you break the whistle pattern here (whistle every two ticks)
00:43:661 (4) - Whistle at begin. You have a whistle on "te," feel like you need to finish this by adding on "mo" too. Not only this but the sound at begin of this slider in background sound good with whistle too. Applies to Hard & Insane as well.
01:11:506 (3) - Use (4) shape instead?
http://puu.sh/Kast01:17:254 (2,3) - To keep to the same idea as 01:19:051 (2,3) - Do something like this (just a quick example)
http://puu.sh/KasXI feel like this is your least polished diff, it's good, but some pattern seem a little off for me (I'm only talking about aesthetic stuff here, rhythm, hitsound, etc. are all fine to me).

00:14:380 (5) - It's better, was going to suggest move the middle anchor point one grid right, but then I experiment around a bit and got this, try ctrl+h, I think this is perfectly symmetrical.
364,60,14380,2,0,B|300:24|256:60|212:96|148:60,1,225,6|6
00:33:422 (3) - I think it would be better if you use the same shape as (4)
here.http://puu.sh/KaEs 217,208,33422,2,0,B|195:155|195:155|165:133|165:133|144:81,1,150,4|12
00:37:015 (3,4) - Can you make like this?
http://puu.sh/KaVh Current pattern always make me feel like I need to wait longer before I need to hit (4) since (3) isn't pointing to (4).
*Follow all or don't follow
00:40:428 (6) - Prefer no whistle at end here like Insane
00:48:871 (6) - Odd to me, there is a whistle on 00:48:671 in Insane but not here and then in Insane, no whistle on 00:48:512, but in Hard. So to combine the good of both world, whistle in both places for both diff.
** Reason: It feel like all the sudden, a whistle appear, adding more whistle help make that whistle feel less sudden or removing that sudden whistle is good as well.
00:46:176 (5) - Forgot whistle at end?

Please try this hitsound pattern for kiai, .osu file for reference or if you agree with all.
http://puu.sh/Kbmj Explanation: I understand you're following piano, etc. with whistle, but this song has a very unique "accents" to the music and I think you should use the whistle to represent this instead. If you map the beginning bit which play the same rhythm as kiai, I would suggest the same hitsound pattern. I remove all whistle which follow piano because I do not think it sound good with this, but you can add them back if you think they're fine and you can adjust some stuff if you want, but I hope you try to follow the idea behind what I'm trying to do. This also applies to Hard.

00:15:098 - Listening to the music, it seems there should be a note here, but it's fine if not, I like how it feel like now.
00:35:937 (2,3) - Looking at other diff plus my personal thought, Seem like you should have a whistle on begin of (3) and remove from end of (2).
00:47:793 (3) - You forgot a whistle at begin here00:54:260 (1) - I really dislike this jump, miss this the first time I play through and still miss it from time to time. I suggest doing this with 00:53:542 (3,4,5,6,7,8) -
http://puu.sh/KbAK (Stack 6,7,8 with 00:54:440 (2))
00:55:158 (5) - Since this is in the same combo as previous jump pattern, I thought this was a 1/1 jump not 2/1. I suggest new comboing here, I didn't suggest for Hard since I don't like one note combo in general and there wasn't a jump pattern before this.
Two things I hope you consider, hitsound pattern that I suggest for kiai and the jump in Insane [00:54:260 (1)], the rest is jut inconsistency stuff and my personal preference, overall it's a nice map.
Good luck with rank!
