BackstoryFelicity was a hobbyist from the age of 12. At the age of 16 she moved out and started as an assistant baker in Sugar Cube Corner, which didn't go too well and was fired. After that she tried to make a living off of anything she could find. She was quite depressed about the fact that she couldn't find something for her to work with. One day a pony came over to look at some trinkets she was selling and saw her paintings. He gave her allot of bits for it, and Felicity realized she could make a living that way. After getting recognized she bought a workshop and started an art class
Weaknesses:Unable to bake, annoying, sensitive, easy to scare
interesting, very interesting. Where was she born? What is her family like? Education? Friends? There's so much potential and mystery :D Good start!
You might want to put more detail and emphasis on her painting endeavors, since it's her special talent. One sentence really doesn't do it justice.
