Image with no Fill Light:

specular  in the body is from EZskine

@DCArt: BS3d has most (maybe all?) of the options of photoshop, but applied in 3D, along with brushes to paint over seams, add noise.  I have found a problem with the reference photos, since they are by design flat lighting, the contours tend to darken on the edges where the skin falls away.  Some of the problems I have seem to be with the lighting.  I like a backlit image, and if using Rembrant lighting, there is no or little direct light on the eyes.
