Price your Artwork realistically.
You must step back and objectively evaluate the significance and quality of your art in relation to all other art. You must also objectively assess your art world accomplishments and determine how they position you in relation to all other artists. These are difficult tasks and not necessarily pleasant, but they’re absolutely essential to achieving the goals of making a go of it as an artist and of selling art.
The more aware you are of the big picture, of what other artists are creating, how it’s being priced and marketed, and who’s buying what for how much and why, the better prepared you are to price your art sensibly.
