This one was an exercise in frustration. I had a nice, loose finished apple with lots of character but I kept touching-up to the point where I'd nearly repainted the whole thing and it lost all its zing. So I wiped it out with linseed oil and started again. The result is above. Not nearly as snazzy as the original but an important lesson was learned... don't overpaint!
