This is the Epic Ruined Librarium from Forge World.
I bought this model, partly as I like the model and partly as it would seem that Forge World were deleting their Epic scenery. At the time of buying this, you could no longer get the Cathedral or the Tank Factory for example. Now none of these models are available.
One of the key things you need to do with virtually all Forge World models is to give them a good wash.
When the Forge World models are cast, the mould is given a spray (I guess) of some kind of lubricant to allow the cast model to be released from the mould easily.
However the lubricant also acts as a barrier to paint, so as happened with previous models I (and others) have painted is that the paint flecks off.
Washing the model in water with a drop of washing up liquid should remove the lubricant.
Avoid using hot water as this could warp the resin (a useful tip if you need to warped resin back to its original shape).
Once washed the model is then ready for painting.
I decided to give the model a black undercoat using Citadel Chaos Black spray paint.
First stage following the black undercoat was to give it a heavy drybrush of Codex Grey.
Next stage was to drybrush with a lighter gray, Fortress Grey.
And then followed that with a light drybrush of Skull White.
