'Tom T' asked me to post a little about how I paint my faces. Very simply is the right answer, I have given this one eyes as he is on a command base.
I start with painting a base coat of Flesh b from Foundry. When the coat is dry I give It a wash of brown Ink, them highlight with Flesh b again. The most Important thing I think Is painting in the crows feet next to the eyes and maybe a line across the forehead and as much facial detail as you can make out. Oh well I told you It was simple. For this guy I mixed 50/50 Flesh a and b to get the shade colour as I didn't want It too dark. I hope this helps Tom.
