Awesome, simply awesome.
I have come to the conclusion that having an artist, who happens to paint bikes, do a paint job is a conumdrum. There are a lot of great painters out there who can lay down a few coats of single color and repoduce your factory finish. It's a noble step in a faithful reproduction/restoration.
For me, having someone like Dr. D do a bike would involve surrendering to his creative talents and having him create my bike. I can see collaboration on a theme or a direction but I would have to let the artist be himself with the final rendering.
I have, in fact, done this exact thing with a frame currently being painted by a well known regional painter. I know the colors being used and the theme, but that is it. When the bike comes out of the packaging it will be my first time to see how his vision translated to the bike. I can hardly wait.
I hope to someday have a Dr. D piece. I can guarantee I would not be asking for a single or two color factory recreation. YMMV.
