Since I decided I finally have time to mod, and since SG was modding Vicho's when I started this mod, here is my mod.
JoJo's EasyAesthetics mod:
00:37:685 (5) - Move this downward a bit so that the end of 4 is directly on the slider track
http://osu.ppy.sh/ss/286625 (looks slightly better imo)
01:05:770 (2) - rotate this so it does not overlap 01:06:621 (3)
01:23:429 (3,4) - the stacking makes this area look worse imo, not sure what you can do though
01:25:770 (1,2) - move 1 so that it is directly on top of 01:27:472 (3) (barely off ds), and then rotate 2 so it does not overlap 01:24:493 (5) (well you might need to change a bit more than this to keep your pattern, but I do think you can make the pattern look better than it is currently)
01:43:217 (1,2,3) - move this all downward so 3 does not touch the hp bar? (things don't look that great when they overlap the hp bar)
Combo mod:
00:30:876 (3) - new combo to be consistent with 00:17:685 (1) (I know this note is half a note earlier, but I think you should have a new combo in the area)
00:35:983 (3) - new combo to be consistent with 00:22:366 (1)
01:19:387 (3) - I would put a new combo here to be consistent with 01:05:557 (1) but since the pattern changed, I'll leave you to find the ideal configuration (just wanted to point it out)
Saten's Normal: (I am really not liking the overlaps in this diff. This diff looks extremely messy imo (mod is going to be lenient on overlaps)
Style/Aesthetics Mod:
00:54:683 (2) - make this slider more balanced
01:08:323 (1) - 01:05:770 (1,1) - this overlap doesn't look that great imo
01:10:025 (3,2,1) - this overlap doesn't look that great either
Combo mod:
00:20:002 (1) - Why did you add a new combo here? I didn't see you break any other similar sounding combos into smaller combos
Tuhard:Style/Aesthetics Mod:
00:25:344 (3) - since this has 2 repeats, it is a little easier to play the next note if you reverse section on this slider (you might want to mvoe the slider a bit as well to avoid stacking issues if you do this)
00:47:472 (5) - adding a slight curve to this slider help make it fit better with 00:47:898 (1) (also same thing as above)
Combo mod:00:37:685 (3) - new combo to be consistent with 00:24:068 (1)
Wmf's Taiko: fine
Rika:01:20:025 (5) - as I told you before, this plays like an antijump that breaks the flow
=====================
Saten's diff is not exactly to my liking especially since I know Saten can do better, but besides that, decent mapset. I'll decide what to do after you mod I guess...
