My version has always looked cartoony and not-real. So I attempted to repaint it with somewhat crisper edges and better-defined shapes, but without over-illustrating it. Didn't work so great; I faced the same problem as the first time I painted—not having any real reference.
I didn't document that step, because it looked about the same as the original. Ultimately I decided to remove the house and trees altogether.
I suspect I'm not done "fixing" this painting.
