Easy:
01:37:240 (2) - this would probably look better if it was a curved slider that followed 1
Emdyion's Normal:
00:17:140 (3) - new combo for new line of lyrics?
00:48:040 (3) - ^?
01:03:640 (2,1) - it would look a little better if these 2 sliders did not overlap each other
Hard: fine
Collab Potato:
00:54:940 (4) - with this note being covered by almost every note before it, it looks like a mess imo
01:03:340 (1,2,3,1) - looking at the overlaps, it is not very symmetric, and I guess that is contributing to how it does not look as neat as it should (normally I find the pattern fine....)
01:27:640 (3,4) and 01:31:690 (2,3) - not exactly sure what type of thing you were trying to make with this overlap, but I don't think it turned out that well.
Ozzy's Portaikol: fine
==========================
Decent mapset. I didn't find much wrong (mostly just personal things), so call me back when you did the changes you want.
