With the application of a black under coat then 'over brushed' with a medium grey the castle prototype is starting to look more like a finished product.
The door was made from a scrap of balsa that I had at hand. Not very convincing I'm sure you'd agree, I think this that it needs some kind of stone frame to go around it.
No so bad from a distance.
The battlement bracing have worked well considering that they were the off cuts from the merlons.
Still working on a stair case to finish the narrative of the structure. I am considering magnetising the joins between the castle components. This will add to the robustness of the structures during game play.
