This sounds cool! I'll give you two characters, but you don't have to use both.
Name: Amelia Brightman
Age: 16 or whatever else fits.
Part: One of Pete's girlfriends, or whatever fits best.
Grade: 11
Appearance: Chin length, naturally blond bob that she's dyed red. Not a really bright red, but y'know, red. Blue gray eyes, light skinned, has some light freckles on her nose. Slightly curvy, weighs 100 pounds, is 5'3".
Personality: Shy, sweet, a little naive, likes to make jokes.
Clothes: Vintage band tees, denim skirts with funky leggings underneath, armwarmers, ballet flats, and usually some sort of headband. Has a bit of an obsession with shoes, and owns several pairs of them.
Anything else: Her parents are dead and she lives with her sister (My other character.) and her sister's girlfriend.
Name: (Mademoiselle) Nora Brightman
Age: 24
Part: Teacher
Appearance: Has shoulder length, platinum blond hair, bright blue eyes. Fair skinned, but not pale, if that makes sense. 5'5", around 110 pounds. Fairly small in the chest area, if you know what I mean by that. Has sort of a pixie-ish figure.
Personality: Can seem a bit cold at first, but she isn't so bad once you get to know her. If the students are halfway decent to her, then she'll be nice. If they aren't, she won't hesitate to punish them. The kids that behave well like her a lot, and the ones that she has to discipline hate her guts.
(If you're auditioning for a teacher) Subject: French.
Clothes: Mainly wears sundresses, button up shirts, straight leg jeans (Not skinnies.), and something like this (Sorry, I fail at description.);

Anything else: She's a lesbian (Has a girlfriend named Matilda who she wants to eventually marry.) and she likes to cook.
Hope you like them!
