How do you know the usual definition of entropy, that is, the one with logs and a Boltzmann constant, wouldn't work for a painting? It isn't obvious that it shouldn't work. You haven't proven that a direct computation of entropy wouldn't work.

It makes sense that it might work. For example, a painting showing human figures has less colour variation than random paint splatters, which means more orderly molecular structure, which means lower entropy. So you can't just rule out a pure entropy calculation.
