The dark circles were a surprise to me too, and I'm not sure I like it either.
My main complaint is the eyes. It's either the eyelashes that have gone overboard, or eye colors go way too dark at the top half. Either way it makes the pupils indistinct and even from a short distance makes eyes look half closed and lidded, which impacts the character's neutral expression a lot. Coupled with the way eyebrow 6 seems angled downward a little more, and my friendly, non-judgmental Elezen (who I've been with for 10 years) now looks decidedly less friendly...
