Clifford showed a series of paintings with symbols and icons from American Popular Culture. His work is an art directed to us, about us. His subjects are our heroes, embodying those qualities most valued by our society. His paintings with figures possess charm, power and dignity. His landscapes allow the viewer to be for a moment in another time, another place not encumbered with the pressures of today. His still-lifes have a fresh approach to beauty as well.
Clifford is a realistic painter of the highest order. His mastery of drawing enables him to capture texture, surface, and detail with extraordinary verisimilitude. Yet, within his realism lies an idealizing tendency; his figures are larger than life, heroic and exceedingly beautiful.
