I don't do many drawings that are geared towards girls, so the colors in this (though largely leaning towards the gray end of the spectrum) were interesting to work with. I like to have some weight to my drawings, and most of the time what that means to me is dark tones. So trying to work with some pastel pinks and purples, I had to find other ways of bringing visual weight and interest. I think it handled pretty well in the end.
I feel like I've seen a ballerina pig somewhere before, probably in a children's book. So I looked it up. And realized that apparently it's not uncommon at all. It would seem dancing is a natural pastime for the swine population. I also found out that Albert Einstein once called ballerinas "athletes of God".
