I noticed some similar strangeness on my Raava Viera character's eyes too- it's like there is a weird super dark "half-moon" over the top part of her eye that really changes how her resting expression looks.

Her skin is also constantly glowing as well in the character creator, which looks very odd on a character who is supposed to have deep skin, but this at least seemed to be mostly alleviated in the actual benchmark test scenes.

The most significant issue I have with the update is the drastic change that was made to my character's hairstyle, specifically the highlights:



The front of her fringe and her braid have had their highlights completely removed and I'm kind of devastated. As you mentioned, this isn't something I have any ability to change as it is inherent to the hairstyle itself which is extremely frustrating.
