When I needed ideas about her, I stumbled across the song "Hazel Eyes," by The Darkness. That song gave me the idea for her eyes, and for something more for her life.
So, she's actually Scottish. Yes, she's currently staying a lot distant from there, but she sometimes gets back to her hometown (which I haven't yet decided). In this picture, she's sitting along a river, wearing a traditional Scottish dress (blame Google™ if it's not correct).
