General:
Slow miku song ;_;. Anyways I really don't think this song needs kiai time imo. I suggest removing it. I don't hear much "epic" in kiai time. If you want, you can use kiai fountain instead.
Kiai times are inconsistent. If you want to keep kiai times, make them the same for all diffs please.
Easy:
00:54:790 (1,2) - You can read on how to make these
elbow sliders with
this guide. 01:21:421 (2) - Make your arc a better curve?http://osu.ppy.sh/ss/169279
02:23:921 (1) - Add a note here? Add whistle hitsound too. It seems kinda bland to me since you can hear Miku sing this part before she echoes. You even did this at 02:41:312 (1).
02:41:312 (1) - Add whistle hitsound?
Normal:
00:32:508 (2) - Add note? The way you've been mapping, you've been getting all 1/1s, so this one felt awkward since you skipped it.
Nothing else I guess.
Hard:
00:12:127 (6) - Move 5 grids right to center it between the two sliders? It's a hard so I think players will start reading approach circle more instead of DS.
00:15:388 (5) - 4 grids right?
00:24:356 (6) - Turn this into a slider instead? Gap seems awkward since you can hear Miku hold a note.
01:06:475 (6) - Change this into 2 1/2 notes with the second 1/2 note as a slider? They would still follow the vocals but better since the slider will act as the hold note.
01:08:649 (2) - ^? 2 1/2 note with 2nd 1/2 note as a slider?
01:20:877 (5) - Add whistle or finish hitsound? You can hear the piano/keyboard (I think) in the music here.
