I always loved the models too, I think a lot of people would disagree with me but I think the features we can pick all look pretty realistic if you put the slightly angular style aside, it was always just flat with the textures. My guy looks a little dirty, and like you mentioned, pretty stoned looking, but overall I agree it's a step in the right direction. I think beyond more visual passes to clean them up, we could use a way to move or resize our features. I got lucky and my guy seems to look just like me but my friend's eyes are just a little too far apart. In addition to everything you're asking for, I think being able to move stuff like that or adjust hair length without changing the hair style itself would be huge for player expression.
