Hey there,
Tails
00:16:564 (5) Whole slider with a finish sound?
01:47:407 - 01:48:081 (3,4) Both 1 grid left, because 3 touches 2 (doesn't look nice)
02:00:722 - 02:01:396 (1,2,3) All 1 grid right, because of the spacing from 3 to 4.
03:20:062 (1) Put the end of the slider 1 grid up, so it looks symmetrical.
03:29:710 (2) Should be symmetrical like 2 in 03:32:407.
Knuckles
00:08:980 (2) 1 grid left.
00:18:755 Put in 1 hitcircle?
03:04:935 (5) Should look more symmetrical (I know, I like "symmetricalism" xD)
Bobo
00:20:242 (4) 2 grid right 1 grip up?
00:30:384 (3) If something isn't a stream, I don't like overlapping notes, pls try to fix this
00:39:654 (1) 1 grid left.
00:53:811 (6) 1 grid right.
01:03:587 (5) 1 grid up.
01:07:800 - 01:08:811 (1,2,3) All 1 grid right?
02:39:317 (2) Remove this hitcircle, because it's starting with the equal ending of 1?
Super Sonic
00:22:463 (4) 1 grid up.
00:26:171 (4) Should look like this after you put it 1 grid right

00:29:036 (6) 1 grid down?
00:38:811 (2) 1 grid up.
03:10:834 (9) 3 grids up.
03:14:542 - 03:15:216 (2,3,4,5,6) Should like like this
