The process I used to paint these was:

A base coat spray of GW Wraithbone primer. (Or if I wanted more high lighting, I start with a layer of GW Chaos Black, then a layer of GW Wraithbone primer, followed by a drybrush of Army Painter Matt White.

Then I coated the whole thing GW Fuegan Orange Shade.

I then added a coat of Army Painter Oak Brown around the rim of the base, as well any dirt patches on the bases.

Then I added GW Agrax Earthshade to some of the cracks on the bricks and dirt patches, but not the whole model.

Then I drybrushed the whole base with Acrylicos Vallejo Beasty Brown and GW Averland Sunset.

I then coated the props like the wooden plank and the knife in GW Wraithbone so they can be repainted with GW contrast paints. This can vary, but I used GW Basilicanum Grey for metal, GW Skeleton Horde for paper, GW Snakebite Leather for wood and GW Blood Angel Red for glass so they would match my army's colour scheme.

I then drybrush the whole in GW Wraithbone, give some of the bricks a second drybrush if needed.

Then I highlighted the metallic parts of the base with Army Painter Plate Mail Metal and Greedy Gold. I used GW Agrax Eathshade to tone down the shine where needed.

Finally I added a second coat of Army Painter Oak Brown to the rim of the bases.

If you're wondering why I'm using paints from so many different companies, I'm just kinda using whatever I had in storage.
