It's not the number of strokes. That doesn't matter in any art form. But painters definitely sometimes have regrets about not leaving a picture alone, tweaking after it had reached its optimal point. I used to do digital art and I'd backup along the way, just in case I overdid it. Sometimes when you're in the moment you can get caught up in stuff that you only realise was a blind alley with the benefit of hindsight.Yes, but my overpainting analog was about the produced music. How can you "over-" anything when the responsibility of the end product isn't yours? And quite honestly if painters are actually debating about amounts of strokes they seem to have similar problem that we are having here.
