few suggestions
general
00:22:262 (2,4) - this overlap doesn't look nice imo try to move (4) a bit on the right
00:57:543 (1,2,3,4) - unstack would be better because you didn't stack notes before, and I think it's the good way, since stack force the player to make an awkward movment
hard
00:02:614 (4,5,6) - it would be nice if the spacing between was the same
00:34:304 (3,1) - mmh what about keeping the same pattern than 00:34:093 (2,3) - ?
normal
00:27:121 (1,2) - you should make them parallel it'll better visually
01:14:445 (1) - whistle is missing on its tail imo
01:16:135 (4) - what about NC here and unNC at 01:18:670 (1) - ?

that's all for me, good luck!
