I've just come across this site The Composites via SimonNRicketts on twitter and I thought you might like it. It is images created using law enforcement composite sketch software and descriptions of literary characters. Which is to say the author's physical description of the character is fed into the software and the resulting image published. I rather liked Tess from Tess of the d'Urbervilles but Edward Rochester (scroll right to the bottom) looks like the missing link. Pinkie Brown and Keith Talent are good ones. You can suggest characters for inclusion too.
