The painter is the first viewer

The more that an artist develops an image, the more risks are created of the image being deficient/insufficient.

That is not an argument against development.

It is an argument for it.

One is seeking to open as many doors and windows as possible on one's conception across the surface of the painting. Those doors and those windows ultimately exist in the viewer, and the painter is the first viewer.

The more deeply an artist draws upon the original conception, the more that each successive layer ignores what is already on the canvas.

Ha ha ha!
