General:
-- To be honest, I can't understand why you haven't mapped the break. I usually don't like to suggest parts to map, but I don't know why there is a break. The lyrics are keep singing.. :~
-- You should Increase the volume at the kiai. 50% is too small, consider pulling it up to like 70.
-- For the last spinner, end it at 01:28:160. The song ends here.
Genin:
00:58:375 (1,2) - Start NC at (2). That will look better with your pattern.
01:05:232 (1,2) - ^
01:12:089 (1,2) - ^
01:18:946 (1,2) - ^
01:21:946 (2) - Placing at (252,184) will make a better blanket.
Chunin:
00:32:875 (4) - This was a symmetry pattern, but well since the rhythm wasn't symmetric, the distance in 00:32:232 (3) wasn't the same. So I suggest to NC (4) to make players less confused with distance. This also fits the song~
01:12:303 (3) - Well, 4 repeats isn't quite expected in this kind of slider.. Replace with 3 1/2 sliders please.
01:17:446 (2) - 1 Grid down.
Jonin:
00:24:732 (5) - Delete Whistle at the end. This sounded quite noisy for me,,
00:31:375 (1,2) - I can't say this is a nice jump. I hope this was a mistake ._.
00:32:875 (4,5) - ^
00:59:018 (3,4) - Give a curve at (3) heading (4) to make a better flow.
01:13:803 (3) - NC this. Current distance is kinda confusing because of the jump at 01:12:732 (1,2).
Kage:
-- Stack Leniency 5 because 00:58:160 (1,3).
00:02:446 (4) - ctrl+G? A perfect symmetry pattern would rather be nice.
00:07:375 (5) - (390,281) to make this stack. (note : this is because it's getting affected by stack leniency 5~)
00:13:482 (2) - Delete this? I can't here a stream at this part of the song.
00:24:946 (7) - Delete Whistle? As "Jonin"..
00:38:875 (2) - Make the distance around 1.50x. A long note didn't felt nice.
01:09:946 (2) - I think making the end Whistle than a Clap will sound better.
01:16:803 (4) - ^
