Yes, please rework elezen, the tiny heads are awful. Simply add better proportioned heads as new faces, so that people who are fans of tiny heads can keep them(tho I doubt we would see many). And add more faces in general(Aymeric type of face).
Please, especially rework the proportions of face 3(the only youthful elezen male face), it almost feels like someone made its proportions even worse than the other ones so we are forced into picking the old looking faces.
And while you are at it, add one extra running animation for every race. The male elezen running animation is atrocious, make one that will be a bit more rough and less stiff.
