Cheers Kriegsspiel and thank you for the kind words
The airship is based on a Revell 1:720 scale Hindenburg model. Wonderfull kit - and huge too: about 35 cm from nose to tail.
From memory I think the cathedral was painted with layers of drybrushing based on a catachan green (Vallejo equivalent) with some white added for the highlights. though it's been a while, so there's probably some chaos black mixed in there as well to make it look greyer. Getting the right color on one off pieces like this is never an exact science. I think I probably started with a black/catachan green mix and worked up the color with layers of drybrushing, adding more catachan green and white. But don't ask me about the exact ratios. For something equivalent for a larger army, i'd probably mix a pot of black catachan, a pot with catachan and a mix of black and a slight bit of white, and probably some catachan green/white for the top highlights.
As mentioned I was really annoyed with this paint job since I messed it up the first time round by attempting to drybrush using foundation colors, and the materials used in the kitbash didn't allow me to strip the old paint off properly.
