On this:
I used a base coat of Deneb stone (Vallejo Panzer Aces Light Mud is very similar), wash with a flesh / purple mix, re-highlight through Deneb Stone to VMC Ivory at extremes. Basically a very light tan / buff colour.
Bruising and deep recesses glazed with a touch of purple again (watered down, very little on the brush). Keep that subtle.
Eyes glazed blue, red glazed into the nose and cheeks. These need to be very gentle; you want to shift the tone just a little to give the face life, not apply it like makeup.
