You posted on my queue a long time ago orz.... here's my mod.
General:
The center circle for the spinner is very hard to see, maybe color it black or something so it's visible?
You do know that there are different colors throughout different difficulties, right? (in case this was an oversight).
Rinko:
00:30:165 (1,3) - A bit too square to be wrapping around (2), fix by adding more nodes.
00:32:458 (5) - Not symmetric
01:39:337 (1) - Move up to fit against (5), don't forget to adjust rest of combo accordingly.
01:53:859 (1) - Curve is a bit too sharp to wrap against a circle.
Manaka:
00:55:770 (1) - Don't think this needs to be a new combo
01:08:381 (4) - Not symmetrical, and doesn't wrap around (1) properly.
01:50:228 (4) - placement feels awkward, would have expected it to continue the flow from the arc at (3).
01:55:006 (3) - Asymmetrical
02:00:356 (1) - move endpoint up one grid so it points into (2).
02:23:668 (5) - Too flat against (4)
Nene:
All notes before 00:07:426 - I think the combos are placed kinda randomly, maybe reset the combos before here, then place them at:
00:00:356 (1) -
00:03:031 (1) -
00:06:088 (1) -
If you want shorter combos, then you can also place them on:
00:01:884 (1) -
00:04:941 (1) -
00:29:591 (1) - not NC
Love Plus:
00:03:413 (1) - Looks ugly scrunched up like that, try making symmetric and with more arc.
00:26:916 (3) - Symmetry- raise endpoint by one grid, right 1 grid.
01:14:305 (5) - A bit too sharp
02:58:827 (1,2,3) - Not quite rotationally symmetrical; it'd be best to pick on slider, copy twice more, and rotate those by 120 and 240 degrees to achieve perfection.
Pretty song, TBH I was enjoying Love Plus too much to mod it very thoroughly. Star + Kudostar!
