Help designing a character?

I'm working on a new story lately, but I just can't decide what the main character would look like. I thought it would be interesting to see how others would picture her.

The character is a 13-year-old girl named Brooke. She's from a rich family, and because she rarely ever spends time with her parents, she's always trying to get their attention, making her pretty stubborn. She hates being ignored. Brooke's always been able to see bizarre things others can't (the story's a fantasy, 由 the way), and because of her curiosity, she often searches for that weirdness, which almost always results in accidents and detentions. She is, however, determined to prove that what she's seeing is real. She claims that she doesn't care what others think of her, but secretly longs for her parents' approval.

I've only recently started working on the story, therefore I haven't spent that much time on the characters yet. This is, however, the basic idea for Brooke's personality. So, what does she look like to 你 after 阅读 that description?
