By sharpness I guess you are talking about the contrast, judging by your
previous message.
Things to check are ambient, diffuse, and highlights (specular and/or
phong). All should be low, near-zero or zero. When it comes to a perfectly
flat mirror like yours the specular highlights are not easily dealt with.
Reason being that you want concentrated intense highlights but what happens
is that it spreads illumination across the whole surface when camera and
light ray paths are nearly aligned. This isn't happening in your scene
though so it is probably the diffuse value needing to be lower. You can
also use reflection_exponent 0.9 (example) in the finish statement to darken
the non-bright parts, leaving lighter objects to show as brighter.
