Finished my Barricdes this week :)
So start off with Wraithbone spray.
Wash with 50:50 Seraphim sepia and Lahmian.
Then Drybrush ceramite white all over lightly with a heavier drybrush near the top.
Then add AK interactive streaking grime to the recesses and leave for a few mins before hitting with odourless white spirits.
Then chip with a mixture of dryad bark, Warplock bronze and chaos black. Use a sponge for this.
