It takes more time to rework a painting than it takes to fill in the canvas in the first place. I wish I could get them all right with the first coat like many of the old masters could, but seem destined to have to rework to make them even passable.
It would be nice once during my life to go over [to Europe] and study the original paintings of the Masters.
I've found from years of trial that the only way I can work is to make sketches in pencil from Nature, purely as reference material for future use in the studio.
When I see these primitive effects coming into my pictures subconsciously, even though the perspective may be slightly out, I leave them in if it helps the general composition.
