Test with your outdoor beach light and the Rhys texture for D3. I had to turn down the intensity of the lights so that it did not completely blow out the default texture. As you stated, your shader does get rid of that red or yellow 'bloom' that is not a natural skin reaction to light. I also prefer the shadow color as it keeps the skin tones rather than turning gray. The second image is the VSS shader with your outdoor beach light at full intensity. Your shader handles the extreme light well, but as you can see other items in the scene cannot. I would think that perhaps the light response in your shader is a little too muted, as it has to work well with clothing and hair added to the scene.
