A crappy, low rez pic of my little sister, Susanna...EDIT:
I might have her voice Rainbow Dash in an upcoming animation if I can't get Ashleigh to do it, (she does a pretty darn good RD imitation!)
In the mean time, if you like, here is a song she wrote and sang: [link]
(She's good, trust me!)
She goes by "Aeva" online for some reason...
