The miniature has been painted with two, very thin coats of Games Workshop's Dwarf Flesh. The thin paint has acted as a wash and flowed into the depressions of the sculpt and left the Lt. Grey primer showing through and delineating the highlight areas.
All the edges of the shirt have been lined with GW's Ogryn Flesh wash and then Devlan Mud wash has been used in the darker shadow areas.
Painting these areas has really showcased the quality of the sculpt. If I remember correctly Kev sculpted the torso and cross-belts then added the shirt from very thin sheets of Greenstuff. Bloody amazing!
