Thanks again for the input!
Virgil, I find your indictment a little harsh and elitist though. A "plagiarist" tries to present his work as uniquely original. I do not. I mean, after all, the photographer didn't "invent" John Lennon or the light that day in New York, did he? He saw. I see. We take away a vision from the event that is personal. I also give indelible credit to the original photographer on the back of the canvas.
This painting was only done for myself as a fan of the man & his music. I now learn from you good folks how a real marketable portfolio should be built.
You live, you learn. (Although I'm keeping my camera!)
