The lights also need to be adjusted.

Modify your lights so that you have the following:

Light 1 set to white (1.000, 1.000, 1.000), with intensity set to 125%
Shadow set to 1, Map Size set to 1024. Light type should be infinite.
Should be to the left (about 45 degrees)

Lights 2&3 set to grey (0.500, 0.500, 0.500) with intensity set to 100%
Shadow set to 1, Map Size set to 256. Light type should be infinite.
One on each side of the figure (one at 60 degrees, the other at -60 degrees).

Just say NO to default lighting :)
