Hey man! Well, I simply use watered down Golden Yellow over a Skull White undercoat. I lightly brush it on with several coats until it looks even (remember to water it down, that's the key!).
Then I shade the deep areas with Flesh Wash (again, heavily watered down).
Then I highlight with a nice glaze of Golden Yellow/Skull White and finally highlight the very highest bits with skull white.
Good luck!
