Family for the poor?

Hi guys! Anyways, Iwant to elaborate on Rora's plot a little bit, so I'd like to hav somone play her little sister, Azalea. If you hate the name, you can change it. Since Rora's very happy and outgoing and bubbly, I'd say her sister is the opposite;studious and quiet and a little on the shy side. She and Rora are close, though. For face claim, I'm thinkin Elle Fanning; Azalea's thirteen. Thanks to whoever picks this up
