I too agree with Joe and heavychevy, get input from the artist. It's great to have an idea of what you want, but they have tons of ideas rattling around those creative minds! I had my bike done this past year by Van Goh out of STL. I was thinking linear lines, I prefer the art to enhance the bike, not the other way around. I wound up with nothing I had in mind, other than thin subtle lines and some yellow (on a blue bike) for my wife, the artist was leary about the yellow but even he wound up liking it. Good luck!
