That is our pretty princess Rarity. One of the four Crystal Princesses, she’s also the Princess of Unicornia (a kingdom of only unicorns). (of course in G4 she was knocked out of her spot and Cadence took her place as a Crystal princess and took the role of a snotty fashion designer) She’s a very playful and sweet spirited pony which is why her smile is so big and why she has that cute bow on her tail. She also starred in the MLP movie: “Runaway Rainbow“Anyway I drew her long hair and gave her crown because this is my version and I really think that a long mane and tail would make her look a little more princess-y. I already drew Rainbow Dash, next up is Minty and Pinkie Pie. Rainbow Dash: [link]
