Don't let one @$$ stop you, Mark - let it be the driving force for you to create even more outstanding works of art. Some folks just never can be pleased, and it appears as if you've run into one. I've come across them myself in other hobbies (3D graphic/game design), and I've only let it inspire me to reach further and create more. The troublemakers hate it too, and you'll love every minute of their agony
Every single one of us is a contributer in one way or another to the future existence of vintage cycles, and I dare say there is no more important individual then the wizard who manipulates the gravity paint gun to create the fine finishes that grace our machines.

P.S.: Not to say that you don't rightfully deserve some time off. Take a vacation, spend some time with the family. To hell with the paint jobs for a month, then afterwards, get back to the good ol' Deltron goodness
