Queen Magda Vamish is my least-solid character right now. On a personal level, I don't really like her, but I also don't find her interesting, so she's breaking the rules of the Disney villain to say the least. Part of it is a dialog problem; I could probably re-write some of her lines to sound less stiff.
When I first started writing her, I was thinking, "Oh, she's really stiff! Humorless! This will be great." But really, I think it'd be better if I went back and wrote her to be funny in the degree to which she is stiff.
