Well, me being a professional painter of the more traditional kind, I can safely say these guys lacks a little in their art education and the all look quite similar to the drawings my 5-year old son does.
That being said, anyone of those drawings would probably have a much greater chance of ending up on a high-profile gallery or museum wall than any one of my "serious" pieces.
Now, how come the other way around wouldn't be plausible? Why couldn't I become a world famous footballer even though I am at the same level as my five year old kid?
I'm a bitter old fart.
Oh, and I'd be willing to bet Michael Owen strained his calf or something drawing that picture and will be out of the game for a further 60 weeks.
