I was looking at this diorama and something just didn’t look right about it. It was the floor, to me it did not match flat against the everything. After watching a LOT of Dr Who recently to get inspiration for this project, you will notice (especially with the recent series’s) that everything is metallic and shiny. With that in mind I decided to not to weather this build except for the air vents, then using my airbrush I gave the floor a coat of rose gold to bring it in line with the rest of the structure.
At first I was uncertain of it until the paint dried and Daleks where placed within. You will see further down with what I mean!
While the floor was drying I then set to painting the backs of both the walls, with this being a single sided diorama, the backs of the walls were painted with a watered down solution of black acrylic paint. This stops the blue foam bleed through when light is been shown from the back. To help applying the paint I used a sponge to spread the paint evenly across the surfaces.
