Have you seen Brian J. Davis’ Tumblr site, The Composites? http://thecomposites.tumblr.com/
It’s fascinating. Davis makes police sketches of literary characters, based on the book description. In other words, we can see how the author portrayed the character.
Wait until you see Ian Fleming’s James Bond! Not quite how any of us might have pictured him. Recent sketches include John LeCarre’s George Smiley, Stephen King’s Carrie. Davis did a few sketches of George R.R. Martin characters.
It’s a fun site. You might want to check it out.
