In reponse to a BOLS post.
Hi, probably not the best way but this is the way I do them.Firstly I don't join the two sides until the end.
1. Chaos Black Undercoat
2. Khemri Brown Basecoat
3. Heavy Drybrush of Bleached Bone
4. Wash Devlan Mud into Joints, Neck, Eyes, & Mouth.
5. Highlight the Edges around joints, head and ribs with B. Bone.
Base is just neat GW sand and base edge in Khemri.
For Shields etc. I use the Scab Red (basecoat Scorched Brown, Highlight Blood Red) theme.
They don't look too bad and no they are not smiling, they look fierce :)
