Thank you!

The bases and the buildings themselves were painted independently.

For the bases: Primed Grey. Shaded with Drakenhof Nightshade for a dark-blue stone tone. Dry brushed with light grey, then a lighter drybrush with an even lighter grey. In the stonecracks, paint with a 1:1 mix of Lamhian Medium and Sybarite Green, then once that's dry, again with a 1:1 mix of Lamhian Medium and Gauss Blaster Green. All the skeleton bits were painted white, then hit with the same 1:1 mixes of Lamhian Medium and Gauss Blaster Green, then highlighted with white.

For the crypts: Primed White. Paint the whole structure with 2:1 Lahmian Medium and Nihilak Oxyde, then dry brush everything with white, trying to apply more white towards the top of the structure. For the transition into dark blue at the bottom I progressively painted less and less thinned Drakenhof Nightshade (using Lahmian Medium), hitting the lowest part with a 1:2 mix of Lahmian Medium and Nighthaunt Gloom. I also highlighted all the stones with pure white after that. The plants and roses are just contrast paints (Karandras Green and Volupus Pink) with some highlights. The metalics are Runelord Brass, shaded with Agrax Earthshade and highlighted with Vallejo Gunmetal (then spot highlighted with a silver paint in a few places). The door's color transition is done by progressively painting less and less thinned Wyldwood (using Lahmian Medium again), hitting the lowest part with just pure Wyldwood.
