Kayn VFX

I really do like the new Kayn skin, and I've been playing him a lot. But 2 things are bugging me. 1: Rhaast's q spin is still the same yellow and purple color, so it'd just he QOL if it were red and black or something like that. But the thing that's irked me the most is that shadow assassin Kayn's face looks so disgusted at all times. Is there any way to make him look less like he's scowling at being alive?
