Uncle Andrew

I told you there would be more posts! Here's a drawing I did rather quickly all the way back in March. As the title expresses, this is a concept sketch of what the character Uncle Andrew from The Magician's Nephew might look like. I tried to convey in the drawing a wizened old man who was somewhat likable at first, while trying to hint at the diabolical evil which possessed him. The first image is the original and the second I manipulated with GIMP to make him more historically accurate. Tell me what you think.
