Poly Painting the Skin

Now after the model was detailed i began the painting process. A lot of it was don't through adding base colours then using "Mask by Cavity" to select lower or higher areas, especially the leather and metal parts. 

The Skin was done by painting layers of deep reds and purples onto the mesh with a rough alpha map, then layering on skin tones to try to simulate the depth and subsurface colours of real skin.
