Someone on GAF posted these and I think they illustrate faces look in both games
HB2 looks fantastic as well here, but there's something really uncanny about the movement of her facial muscles. It seems as if they mocaped her face and then dialed the movement to 11, it doesn't look natural at all. Its hard to compare the scene itself because the tone is wildly different, but HB seems to have the edge in how teeth are represented. The rest I won't comment on because again, the tone of the scene is very different and comparing stuff like eyes and skin shading is hard with such different settings.
That’s from the meta human tech demo, it didn’t look quite like that in the latest trailer.
