I think reducing the amount of finishes here in this difficulty would be better, especially the more denser areas, where there are consecutive 1/1 beats instead 1.5~2 beats apart, but other than that I felt that you should have had those impacts and finishes on 01:09:570 (9) - 02:19:970 (9) - 03:01:570 (59) - 03:30:370 (99) - instead
Futsuu
00:09:570 (16) - shift to 00:09:370
00:15:970 (30) - shift to 00:15:770 - it lands better on the music here
01:20:970 (44) - k instead?
01:34:370 (70) - shift to 01:34:170
01:40:770 (84) - ^
03:01:570 (92) - finish
03:55:170 (203) - shift to 03:54:970
04:01:570 (217) - ^
Muzukashii
00:31:570 (96,97,98,99,100,101) - try dk k kd k, I think that works nicer
Oni
03:02:770 (197) - d instead?
Inner Oni
00:08:570 - should have an object here like a d so that the rhythm here does not feel incomplete, the rest of the song you made it along with the music, but this part feels detached
00:15:170 (50) - shift to 00:15:370 and it can either be d or k
00:27:170 (110) - change to k, have it differ from 00:26:770 (109)
01:22:370 (430) - finish?
02:09:370 (110) - I don't think the finish should be here, rather it should be at 02:08:770 (107)
02:32:770 (246) - finish?
03:43:170 (260) - ^
Good Luck
