This storyboard is sweet. Good job, kaouji!
I feel that the beginning of the first kiai is a little early. Instead of starting right when Rita sings "kimi", start it on the "wa" (01:16:594) as it's the apex of that particular part of the phrase. The "kimi" are more pickup notes than the start big beat that the fountains accent. And after typing all that, I realized that's what you did on the second one. Unify them. :P
Just a really slight thing, but with the pause menu I noticed that the general slant of the border on the buttons look really aliased. Maybe try to smooth the line going down?
Are you sure you want to each each difficulty with a whistle on the end of the low-volume spinner?

01:16:774 (1) - This beat just feels really weird to me, especially when it goes against the vocals that start up right before it. If anything, remove the finish. Maybe move it back to the red tick at 01:16:594 (1), though I don't know if you're one of the ones that is really iffy on putting notes on a red tick. I feel that it's fine considering it'd go with the music, and there's plenty of time to aim for it. When it's on that red tick, the finish doesn't sound too bad either. I can see you start up the same phrase similarly every other time, but I think after the spinner and the pause in the music, it'd fit better this way. Yeesh, quite the explanation, haha.
I had some reservations about sliders like 01:21:112 (3) for newbies not knowing when the slider is going to end, but it's relatively slow, so they might be okay.

00:37:738 (1) - This feels a little short for a normal - especially with the beat so soon right after it. Consider mapping through instead of a spinner.
00:57:979 (1) - Add a finish on beginning of slider?
01:22:196 (7) - I'd make this just a regular beat instead of a slider. It doesn't feel right with the music.
01:38:461 (1,2,3,4,5) - Haha, I foresee a lot of deaths here. :D
02:13:160 (3,4,5,6,7) - I kind of worry if this is going beyond the normal sphere of difficulty though.
02:46:594 (1) - Maybe end this spinner at 02:47:859 instead to give a little more time to realign post-spinner? If you do, remove the clap on it.

00:39:184 (5) - This note is extra compared to the song, but it plays fine still.
01:27:618 (3,1) - I initially had qualms about the spacing between these two, but on the second play through I had no problem. I dunno. It just initially seems far considering the rhythm.
01:51:293 (3) - Remove finish from beginning of slider

*looks at walls of green* I wonder who did this difficulty... :P
And it's way beyond my ability. Can't really mod that very effectively, hehe. Looks fine though.
I sure am long-winded on inconsequential things though. Looks great!
