If you look at the Orc, one one side of his face he seems to have a sort of battle-scarring, in that one of his tusks is broken and his eye is blind. I would say that we can safely assume this means that we can have asymmetry in our character's appearance where in Oblivion what you did to one side of the face was mirrored on the other.
In a rush of news about the gameplay, the fact that Alduin's dragons are the Jills and what that means about his relation to the Imperial pantheon, etc., I'm choosing to look at the little things. So what do all yall think?
