The wonderful Mario character portraits that you see below were created by DevaintArt user ‘Robotpencil‘.  There is other Nintendo related art in the gallery below and my favorite of all the pieces shown here is the Smash Bros. art.  There is also a piece that shows what the process was to create the artwork called ‘Its me Mario‘.  You can see more art by Robotpencil over at DeviantArt but just fair warning some of the other art by this artist is NSFW.
