Thanks Tamer.
Call it artistic license
, without putting in the main doors and ceiling, I wanted to try and capture some of the elements of that scene.
Today I have taken a sponge and gone over the walls with a light grey wash, filling in some the areas I missed yesterday. You will have noticed that I have put back the extra layer of foam core back in, not only to strengthen the floor but hide the bottom of the walls. This has left a few gaps between the walls and the extra floor, this gave me an idea to try something new. I got some grey course ballast, mixed it in with some PVA glue and paint, then used it to file the holes around the edges. I also did the same for inside the little cave but used black instead of grey, making it as dark as possible. I will be using the same technique for the overall floor but using a sandier tone like yellow ochre or something similar.
If you have any suggestions please let me know, especially with the colours. Being colour blind I don't always get it right.
