Hordes: Carnivean (work-in-progress)

Here, the skin areas of the Carnivean heavy warbeast have been drybrushed with Vallejo Game Color White.

After waiting for the drybrushing to dry, I base-coated the chitinous areas with Vallejo Game Color Terra.

I'm trying to decide whether to paint the ridges on his back and tail brown or leave them white.  I'm leaning heavily toward brown.
