I made an account to talk about this (please forgive any formatting mistakes), so I'm glad to see I'm not alone when it comes to finding the changes to Face 3 in particular just...horrible.
I wish I had taken more pictures to compare directly but looking at side-by-sides it's really obvious the eye shape is different now, almost like our eyes are half-closed all the time and it makes the facial expressions look awful. Not to mention the strangeness with the lips.

(the only deliberate changes here are colours)
it's kind of embarrassing to admit, and I know I'll get mocked, but after seeing how she looked in cutscenes and how awful the face and expressions were I cried. I've had to change to Hrothgar just to keep playing but seeing all the changes to Elezen have really been demotivating...I don't know what else to say. I just want my character back.
