[General]
Remove beatmania iidx from tags since it's in the source.
Delete the .osb file.
Change background colour to black?
Another has letterboxing in breaks disabled while other diffs have it enabled; make it consistent?
[Easy]
I recommend shifting either your entire map down a grid or parts of it down a grid; notes such as 01:10:027 (1) which appear to be centered in editor actually end up being 2 level 3 grids above the center in play mode.
01:08:165 (1) - End 1/4 later?
01:16:233 - This break has many unused timing sections in it.
01:55:647 - Eh, this timing section is placed kinda weirdly; the spinner spinning and bonus sounds are silenced...and then suddenly pop out. Maybe it's because of the other diffs; move it 1/1 later?

01:09:302 (4) - An observation; the music is delayed 1/4 here. If you shift this note back 1/4 though, it becomes kinda player-unfriendly. I'd consider actually breaking the pattern and doing something new here, possibly replacing 3 with a slider that could end where the actual note lands.
01:14:785 - Add a note?
01:28:233 (1) - Same issues with the movement of the playfield occurs here; this note isn't actually centered.
01:52:854 (1,1) - Uh oh, the second spinner starts before the first one ends, this is unrankable.
Really liked this difficulty; thought it fit the music very well.
(plus it's right at the skill level that I can comfortably play at, adds a lot to the relaxation XD)

01:09:613 (7) - 1/4 later?
01:14:578 (5) - Same thing as always about centering notes.
01:52:854 (1,1) - Ending a note and starting a new note on the same beat is also unrankable.
Very cool maps, star * 3~
