Did U notice that many NPC have almost the same face? And I dnt know why but many male NPC's seems to me Ragnar from Vikings serial..
and females also have very similar face
I think that goes for every race / character. You have at most 2-3 different facial structures, then beards / hair / skin color or pattern give you a tiny bit more customization.
The only real customization is RACE -> M/F. Beyond that, everyone looks identical, save for beard / hair choice. Pattern for the beast races is an extra layer.
