Done for a Drawing Jam on the actor. About 90 minutes, pencil and Photoshop.
The texture overlay is a map of London's railway system. It's a reference to the movie which launched Ewan's career, 'Trainspotting' in which he portrays a junkie. The 'tracks' going up his arm, was one of those artist's happy accidents which occured while I was positioning the map.
Since he's wearing a suit, I'm also submitting this to Illustration Friday's current topic 'Suit'.
