Even if the more elvish look isn't doable for facial animation reasons, etc., I don't think elves and and humans should share the face presets. It's even more funny when you notice that while elves and humans have identical faces, the half-elves don't share the presets. I think Astarion is an ok compromise in that his face is more slender than that of an average adult man, if we could at least get the same slenderness and grace on the elf presets, I'd be content.
