That is a very similar blue to a Menoth scheme I am currently working on. The red/earth brown works best in my opinion. Here is an example;
Base coat was p3 Bloodstone, applied via airbrush. Highlight was done with p3 Menoth White Base. Then I airbrushed a very thin coat of p3 Brown Ink(mixed 50/50 with water). The final step was to paint the cracks in the soil with
pf Battlefield Brown.
