Thanks, I know the Ork is very static, but I'll do something better for next year
I can't remember the exact recipe for the skin, but it was something along the lines of:
Tallarn Flesh
Wash with a few layers of watered down ogryn flesh with a hint of purple and green (very tiny amounts)
Tallarn flesh
Tallarn mixed with bleached bone
Increasing bleached bone then a touch of white into the mix.
watered down wash again
Rehighlight.
Hope that helps...
Tom
