here we go.

I think you'll need an audio lead-in of 2000 - 2500.
The avg bitrate is~93kbps which is unrankble. Try to find a source with 128~192 kbps. (if it exceeds 192 you can compress it, but it's not recommend to change song with 9x kbps to 128 kbps because the quality's still poor.
make sure you full submit after this ^.
The audio lead-in time's not unique. At least it should be the same for collab and taiko because they start at the same time.
[Taiko]
00:13:990 - k?
00:23:265 - ^
00:39:490 - no problem here, just to say that the trill in music's not exactly on tick. It's about 1/8 beat eariler, same for the coming positions.
00:54:115 - k---d---k?
00:57:302 - a transitional section of the song, it would be nice if you continuously put a waltz beat ( k d d k d d) there. So either d k or k d here?
01:06:490 - add a d ( <- a red note) here?
beautiful piece and nice taiko diff.
8/10
[Collab]
00:21:865 (2) - whistle?
00:35:365 (4,5,6) - whistle finish on (4,5), nothing on (6) would give a nice sudden muting effect
01:18:677 (2) - I prefer whistle here only
01:51:302 - make a gradual change on hitsound.
01:53:365 (4) - whistle
02:09:865 - same treatment as 0:35.
[Normal]
Spacing isn't so stable? 00:01:802 (2,3,4) 0.9x, (4,5) 0.95x, (5,6) 1.02x, 00:09:865 (6,1) - 0.85x ...
In the easiest diff a constant spacing is quite important so I think you can fix them with grid lv4.
00:35:365, 02:09:865 - same as hard collab
deserve a star here.
