So, I had cannibalized these parts from a GW temple of some sort, deciding to make a set of ruins out of some of them, while keeping one set more or less intact. The picture above show the first three stages of recovery.
The image on the left is the dull uninspired original version. The next shows the impact of a fresh, redder swath of colour across the exposed barren surface. The last shows the temple bits highlighted to make them stand out better. After this highlighting, I will add some red/yellow flock to punch up the vegetation, and will no doubt add in the odd shrub that I have converted to a Martian red from the terrestrial green.
