I have a possible face claim in mind. I don't think it will step on any toes. But, I'm not entirely sure about her.
What I'd like is a waifish young woman, severe or despondent, with straight, reasonably unstyled hair, a lifelong disinterest in the opposite sex, perchance with prominent ears.
There are surely a lot of Japanese and goth models that fit those criteria, but I don't see either fitting the setting.
