I love the concept man. I think I did that on acid once. ;-) As you might notice if you check out my two design offerings. Anyway I this is cool man. I would like to see it higher on the shirt but that's just a personal thing. It's cool.
Yeah, the concept is good, but there should be some kind of difference or payoff by the end. Maybe make the first B&W, the second with a few colors and the third brightly colored? Or make each level up a more detailed drawing?
