The first face of Pan.

So, I've decided to do something compleatly foreign to me. I've decided to draw most elements from a piece of artwork separately. Its based on a story called "The music on the hill" by Saki, which features the god Pan, the god of the wilderness, flocks, shepherds and animals etc etc. It's an odd tale in which Pan takes the form of a young boy hidden in bushes and plants to torment a woman.
