Hi D@rth J@ymz,
thanks very much, the black is pretty straight forward, I use GW chaos black as a base, then add a little bleached bone for the first highlight, then repeat with a little more bleached bone twice more.
I use bleached bone rahter than white, as it adds a slightly 'soft' look to the grey as opposed to the grey you get by adding skull white.
hope that helps,
regards
jim
