Thanks for the kind feedback!
@The Sun King - here's the recipe for his armor:
1. Black undercoat
2. Layer of Ghenna's Gold. Needn't be a uniform coat. This can look as crappy as you like. Just need to make sure you cover all the black.
3. Layer of Leadbelcher. Make this a pretty sparse layer. Leave the Ghenna's gold showing in all cracks and recesses.
4. Wash Devlan Mud.
5. Highlight Ironbreaker. This is probably the most important step. Take a similar approach to the leadbelcher layer - stick to highlights, but make sure that not too much of the brown/gold is left showing through.
At this point you can stop. Depending on the topography of what you're painting, it may still feel a little low on contrast or it could be a bit too shiny. If so:
6. Wash Devlan Mud.
7. Layer of Ironbreaker. Similar to step 5, but concentrate only on the starkest highlights.
I developed this approach painting what felt like a million skellies for my End Times army. Good place to experiment with corrosion and bone. Put any failed experiments on the back ranks - no-one will ever know!
