Although Barker's art comes in all sizes, minatures such as "Reflective Moods" (9x12") allows the artist to keep pace with the rapid flow of his ideas.

Because his themes differ so widely from painting to painting, it's difficult to identify a Barker except by the trademark tiny red specks he uses in "negative" space. Most influenced by Milton Weiler and Don Stone, Barker's approach is to "paint light, not things. My favorite piece is always the last one I did." He'd prefer that people not linger over favorites either. "After completing a painting I want people to say to themselves 'I have been there and seen that'."
