Varnish on unpainted canvas

I was doing a study of Roy Lichtenstein in oil on a white canvas (not prepared in any way) as practice. I've just completed the black, and now a friend wants to buy it. So the question I have, is that after it has dried, do I just apply varnish to the entire canvas, including the unpainted portion? Will that look ok?

Picture attached.
