suggestions on achieving this look

The painting is all hard-lit -- the couple are lit from the left side, side-lit, the light coming over the right shoulder of the man so that he doesn't shadow her. There is a frontal fill that is high enough to throw a hat shadow on the man's face, topped with a flag so that the couple's shadow from the fill doesn't hit the back wall. The back wall is lit from below, from the right corner of the frame. Everything is gelled orange-yellow.
