I've noticed a quirk with the narrator voice of one of the two novels I'm working on. This narrator only describes the beautiful aspects of every character's features. You might think the women are all beautiful, the men are all handsome - this one has beautiful eyes, that one moves like a swan - a world of Hollinwood actors.
Only, it isn't. I have a character - the narrator mentions repeatedly his keen gaze and proud step, and once, when the character is first introduced - that he survived smallpox as a child, which thankfully spared his eyes. Other characters mention how this character appears to have two noses, and how enemies flee from the horror of his face. But the narrator - nope. Keen gaze, proud step.
The novel is narrated in 3rd person, omniscient narrator. I mostly follow four or five characters, all well-educated high nobles. They would consider it beneath them to think of a person as "ugly". If they look down on someone, it's in the "oh, they're less fortunate, I should help" way, which can sometimes be misplaced. Commenting on the shortcomings of another's natural appearance would be considered by them crass, a mark of bad manners, something fit for a commoner - not for them. So the narrator voice is in tune with the world-view of the main characters. (With how they believe they should act, not necessarily with how everybody always does act.)
Without sacrificing the narrator's voice, how can I make it clear that my characters do not live in a Hollywood film, that the people are regular people, who, it being ~5t century, do not have access to decent medicine or good dentistry, and it is a conscious choice to only speak of beauty?
