She's based off of that idea, but since I didn't actually go to the effort of looking up the passages in the book that describe her, I can't really say she -is- the Narnia Ice Queen... But that was my initial source.
Well, in all honesty, the Ice queen in this picture is really starting to look (unintentionally) like me. So when I get to shading the face, I'm going to push that idea forward more for -this- picture, and then for the next ones, I'll do various self-portraits in an 'elemental queen' series. I've never done that before, and I think it would be hilarious! Especially since I don't see myself as suiting queenliness.
