Try adding a tightness value.  The default is 50... higher is tighter, lower is
softer.  You might also try lowering the intensity of your lights to a little
more than half of their respective values.
    I'm currently experimenting with the lighting on one of my object concept
scenes, but it's a little slow going.

                    A.D.B.
