Combo colors?

00:26:632 (3,4) - You don't use this structure in any other diff, just change it to 1/1 for consistency?
00:44:757 (8,9,10) - I think turning this into a repeat slider shape would be much better for the flow between 00:44:445 (7,8,9,10,1) -
00:57:257 (1) - Silence?
01:13:038 (2,3,4) - Reduce this cuz its kinda distant from each other
01:19:757 (9,1) - No need for hyper imo, the note has no sound to be emphasized by the hyper. A normal dash or a walk would be more acceptable.
Platter
00:33:115 (3,4) - If this is intended to be a dash, it isn't D:
00:55:070 (1) - inconsistent spinner start tho
00:57:257 (1) - Silence?
01:19:208 (4,5) - Even the top diff doesn't have an hdash between here. I'd suggest making them consistent
Salad
00:27:490 (1) - A curve would be nice here, even though it's kind of a calmer section
00:49:990 (1) - Kind of hard to catch at this angle, either angle it more or curve the slider to make it an easier dash
00:57:490 (1) - Silence the spinner?
01:02:490 (1,2,3) - Distance is kind of high... better to reduce here
01:13:115 (2,3) - A bit cramped here xdd
Cup
00:28:740 (2,3) - Seems a bit close together, moving them both to x:366 and then 00:29:365 (3) - more to the left would be nicer
00:32:490 (1) - Curve is a bit weird, you could probably make this more circular
00:35:070 (3) - forgot an NC here
00:53:115 (2,3) - More distance between here for the downbeat?
00:57:490 (1) - Silence this one?
00:59:365 (1,1) - Again, more distance for the downbeat

Good song. Someone should map this for standard!
