This note 00:07:086 (7086|3) should be moved to the left to match the pitch of the melody, just like the previous note.
Except the 13 doubles, I don't understand how to fix this section.
I think, the Jumps and Hands which you mentioned "have no clear usage", actually have a clear usage.
For the kick, I added Jumps. And for the snare, I added Hands.
The intended pattern is Jumps SingleNote Hands SingleNote Jumps Jumps Hands Singlenote
But, because I think it's too hard, I changed the pattern to Jumps SingleNote Hands SingleNote Jumps SingleNote Hands SingleNote like it is now.
Thank you for accepting my mod request and giving my map an in-depth and detailed review and mods.
I'm going to fix and apply all the changes you have suggested in the timeline. And using your given album as a reference, I'm going to improve some suggested changes using my own ideas.
By the way, I had only a little experience when I started to map this song. It's my second map. The first one I made it back when I just started playing osu!mania 9 to 10 months ago.
