Basecoat with 3:1 Gorthor Brown and Wild Rider Red .
Add general shading with Doombull Brown .
More carefully shade deep recesses with 1:1 Doombull Brown and Abaddon Black .
Add some highlights with 2:1 mix of the basecoat and Ushabti Bone .
Highlight more selectively. For this, increase the amount of Ushabti Bone in the mix, so there is more of it than the base colour. Roughly 1:2 now.
Finish with a few very small highlights with pure Ushabti Bone .
