That GF is absolutely terrifying. Just saying.
I'm not 100% on her having an alien as a pet to be honest; considering that there's only one in the canon and it's a right bastard to find, it's a bit far-fetched that a student would have one as a pet.
Hm... a PuPu-like thing would be acceptable, a robot (despite her technophobia) or voodoo doll or something, but having an actual sentient alien as a pet is a bit much... sorry.
Other than that, looks great.
