Sure u dont have to do anything. But if are to hold urself to ur own standards u set for urself you have cut urself off from a majority of art throughout history. For example by ur own standards then u cant look at anything by Caravaggio, Paul Gauguin, Richard Wagner, Jackson Pollock, etc etc. Whats the purpose of artwork if not to express something. Can you express anything if an artwork is to be judge by ur charecter and not by itself?
