>>90803300She's super cute. Like, really really cute. I don't know what is it specifically about it, but all the elements of her design come together and make up a perfect cutie. Also, these little mannerisms and movements that she does, like chewing her wand, are quite adorable.
But most importantly, her personality, of course. She's fun, but not obnoxiously so. And even though she can often act selfishly, she genuinely cares about people and just wants everyone to be happy. This is important, because you'd think that as the only child, with a royal background of all things, she would be a bitch like Brittney, but Star is actually far from that.
