Whats the Problem?
Personally, I am painting over several of my crappy Mars Attacks sketch cards. [I have a lot of ideas that the "official artists" couldn't have envisioned.] First up Zack G. It is difficult to understand why his feelings would be hurt that people don't value his 30 second Art 101 sketches. These sketches have nothing to with his "Artistic Identity" but were really just quickly done for money. The way I see it... I own that piece of cardboard. I paid 40$ for it so I should be able to do whatever I want with it.
