Without being entirely assumptive I am going to say any art created is a statement of the artist who created it. Art is communication. Some art is so loud and clear that it can be heard and seen from space, and other art is as subtle as a bead of sweat dripping down your forehead. For example, a painting’s brushstrokes on the surface indicate a subject matter’s color, form and texture. It is also an indication of an artist’s working speed, the pressure that they are applying to the surface, etc. There are people who know enough about Jackson Pollocks painting style to determine his style of drips as opposed to another person painting in the same style. I think every artist has experienced a moment where they have taken a step back from what they have created and learned something new about themselves.
