A triptych of quartets. From Auguste Herbin: Clarity. From Andy Warhol: Repetition. From JS Bach: Order. From Antônio Carlos Jobim: Color.
For what it's worth, I operate from this viewpoint: Most canvases, most sheets of paper, look better before someone attempts a painting or a drawing. The simpler an image is is almost always a formula for a better image. I prefer to remove all traces of my hand, just reduce everything to geometry, especially those most perfect shapes: the circle and the square.
