Perhaps screen prints of E Tanks with varying palettes would of been more appropriate.
Here's an Advance Painting project that I did really quick during the Thanksgiving break of that semester when I felt that I should be doing something rather than sleeping off my Itis. It's was done on a rather small canvas and I didn't have much paint on hand, so I had to apply carefully and thinly. It worked out okay in the end, and my teachers and classmates thought it was interesting. Some thought it was some sort of commentary on different races, but really the different colors of the Marios are based on the palettes he flashes through when you get a Starman in the original Super Mario Bros. (They aren't exact, so please waste your time telling me im doin it wrong.)
As for the idea, I just thought it'd be cool to see what Andy Warhol might make had he still been alive to do work on current icons of pop culture.
Here's some shots of the individual Marios:
