Before receiving instruction, Barbier was a self-taught artist for fifteen years. He cites his experience of being a veteran of the Vietnam War (1968-69) as a strengthening factor in his development as an artist. In tackling controversial subjects and themes that often reflect a local context, Barbier employs complex compositions with meanings that are open to the interpretation of the viewer.
He uses sometimes controversial subject matter that can be disturbingly honest with a hint of surprise and humor. His current work is influenced by pop culture movie posters, pin-up girls and the powerful nature of the female form.
