I am using Poserpro2012. Using Colm's IDL lights, same lights in both images. The only thing that was tinkered with was the bump map, all I did was add a 15% noise to it which resulted in the image on the right where the mesh shows through. If it were the lights, wouldn't the mesh show through either way? 

Not my set up, it's the merchants. I'm just trying to give the skin some defination, and rough it up a little bit, instead of having smooth marble like skin.
