NotEye tiles do not always reflect biological sex
Many creatures have biological sex, but their tiles are exclusively masculine
Since ADOM associates biological sex with an enormous variety of creatures, the tileset should reflect these associations. Some of the creatures — like outlaws and bandits, I think? — have beards in their tiles, even when the textual description indicates that the creature is female. I don't know whether female dwarves, gnomes, orcs, trolls, ratlings, etc. are normatively permitted facial hair, but humans and elves clearly are not.
I realize that updating the tileset to reflect biological sex correctly is rather a lot of work, but since the tileset exists to support and enrich the game, the fact that tiles depicting human women often display beards has to be considered a bug. It would seem rather a shame to remove biological sex from the text, since that would amount to removing verisimilitude from the world, so fixing the tileset is definitely the way to go.
