@Ragman,
I have a large bias against him, but that's all from hearsay. I might turn around and like him, someone introducing people to the pleasure of painting.
I was raised by parents who didn't draw (they had other good attributes), my mother saying what some nun in 1909 must have told her, that she couldn't draw a straight line, I gather a bad thing. She was bemused I liked to draw.
I drew pretty well, over all, let's say middling, but when I first started painting I was completely clueless. I caught on to the play of it through smashing good teachers.
