Ruined Shop with Passage
The first stage after washing the resin will be to remove the mould lubricant and then clean the flash from the casting, especially the windows and the doors. Having done this, I gave the model a light white undercoat, hence it isn't white, it still has a yellow tinge of the underlying resin.
I then gave the debris a basecoat of Tamiya Brown.
The next addition was painting the roof tiles of the part of the roof that had fallen into the shop. I used Citadel Terracotta.
I also painted the broken beams with Citadel Scorched Brown.
