When we talk to npc lords, they have this facial feature I like to label "Mid Mouth Breath," and it looks absolutely ridiculous.
You could be the most handsome/beautiful person and if you held that exact same expression people would think you looked bonkers. And that's what happens with npc in this game, they hold that expression and it doesn't matter that they actually look decedent.
Take Ira, princess of the Southern Empire, for instance. Looks great in her encyclopedia page, but meet her in person and it's like you smell horrible and so she's trying to breath through her mouth. Look lady, there's no bathing functionality in this game or I would use it at least once a month!
Taleworlds can fix this issue easily - have the npc lords keep their mouths shut. I don't care if it looks like they are speaking to you with psychic powers of the mind, it still looks better than the alternative.
