Just so you know, the Roleplay type is there to indicate whether this character is meant for World of Equestria (Friendship is Magic G4 show setting), A New Generation (G5 show setting), or Free-for-All (Any setting).- G4
Given that changelings don't normally have cutie marks, I'm assuming that mark is for her disguised form? Which sort of pony is her favorite disguise? That can go under unique traits. (Kindess is not really unique: it's Equestria! Most folks are kind around here)- Yes her cutie mark is her disguised form, her fav pony is Pegasus ( she don't have a fav Pegasus to disguise as).
The history could be expanded and cleaned up. Where were her parents? Did she and her brother move after they passed? Why did her brother leave? What is the closest city/town to the cave she lives in?- Her parents passed, Her and her brother moved to the cave after they passed, her brother left in search of better oppertunities for him, the cave is close to Pony Ville.
Also, please use some proper sentence punctuation; a lot of folks prefer their RP partners to have good grammar.- Got it!
