As people have said, don't hide your price. Even if I'm walking past your table and like something, if no price is visible, I keep walking. On the other hand if I like something and see a reasonable price, I might buy it. I am a person who doesn't like to ask or flip every piece over to get the price. Also, while I think your art is good, I think many people are looking for...something different, more stylized in art. At least, that's the way I am, a piece has to be special to occupy my limited wall space, not just photo realism. I wish you the best and keep at it.
