What defines fine art?

How do you define fine art?  Fine art as I have come to know it falls into two broad categories, two dimensional---various types of paintings and drawings, and three dimensional---various forms of sculpture.  From here the debates are vast as to what ingredients qualify a work as a true fine art creation.  In many walks of life and in almost all products there are definable elements and specific criteria to establish identity.  Let me further complicate what I consider to be a bit of a dilemma.  In the process of arriving at a definition for fine art, what is the definition of a fine artist?  I have worked intently for many years as a sculptor.  What defines or qualifies me.... is it my creations, my perseverance, or some other set of criteria?  Is there a definitive description or definition for one or both, the art and the artist?  Let me know your thoughts and we can perhaps arrive at an answer.
