After my teapots and trying to play with shadows there, I took one of the pieces of sculpture (leather and feathers) and tried to see how it would turnout.
Instead of trying to light the base, this time I tried to get the shadow to follow the sweep as the seamless paper transitions for horizontal to perpendicular to the subject. The hard part is trying to get a balance of light; too much and the shadows disappear and too much and the seamless looks gray.
