They updated ALL the faces, including Tyrians and Canthans for the Nightfall Cutscenes.

does that include the character in game?

i ask as my ele had nothing i noticed

Yes, characters got facial changes. Most of the changes were really small and hardly noticable. The main target of the changes were around the mouths - to facilitate animation during cut scenes, and eyes, where they fixed a shadow problem. The end result is that mouths are slightly open and the eye's have what looks like eye liner on them.
