Polar bear heads

I was watching something on the 2nd disk of the Chronicals of Narnia, the Loin, the Witch , and the Wardrobe. And I have the 4-disk extended vision, (bought with my own money) and I was looking at the cover and I was also bored, so I drew the bear heads, but I also used the muscle thing to help, anyway, one of them I drew without anything to look at though.
