I think part of the problem for some of the races is the eye tilt seems slightly off, which could be an actual issue considering how much focus was trying to give the eyes more life. Having the eye textures sit just a touch off from what they used to be makes a big difference. Characters go from looking intrigued to disinterested (or the opposite seemed achieved with the Elezen male).

There are some other differences as well, of course, but the eyes are what my eyes jump to in almost every post that is unhappy with the changes.
