Ten years ago I would not have dared to paint foil, it looked too frightening, too complicated.
This is now the fourth painting of mine with foil. I wouldn't say that it has gotten easier to paint, but is always very exciting. The value (dark and light) and color changes are very subtle; you really have to slow down and look carefully before putting the brush on to the canvas. It's almost like painting in black and white...
... but not really.
