Are you aware that this surface will never catch any shadows, because it 
is purely reflective (due to the black pigment)?

Also note that with HDR (i.e. radiosity-based) illumination, the 
brilliance, specular and roughness parameters have no effect.

You will also never get sharp shadows in this manner (though you can 
improve the sharpness of the shadows by specifying a low maximum_reuse 
value, of course at the cost of rendering time).
