A different take on the excellent new film (seriously, go see it if you haven't). 
I highlighted the main character's knightly, almost saintly qualities, and used an art nouveau vernacular to suggest that he is transcendent, but still pretty earthy. 
Like the character in the film, the figure blends into the background and is one with his machine. The halo is a clutchplate, which seemed appropriate considering the shifts in behavior and morality he makes.
