Sorry, but I'm never impressed by these guys. It's not a skill that's necessarily difficult to do.. paint is a VERY forgiving medium. The most challenging part about that is doing it upside down. What I AM impressed by are the people who ask the audience what they want to see, and go at it with zero practice or prep time. Dunn's probably done Ray Charles hundreds of times... nothing too impressive. But someone who can ask the audience what they want to see, and they say "a sheep flying around the Empire State Building", and the artist turns around and knocks it out... now that's impressive.
