These are two different versions of the same illustration, both of which are in fairly preliminary stages.  This character is the narrator of the story, Dr. Nicomachus.  He is a mysterious individual who lives in the Speculative Realm and studies thought experiments.  Since he does not actually exist in the physical world but in a sort of mental space, I thought it might be fitting if his anatomy does not obey all the rules of physics, hence the unraveling arm and hat.  The object in the hand of the version on the right is a double image: both a cane and two mirror images of Mr. Doubus's face.  In general, I think I like the posture of the left version and the cane and arm position of the right version, so I will probably find a way to combine those elements.
