Having gone back to my Ork Fort I decided to give the roof floor a wash of brown ink.
Now I have done this, I will drybrush the floor of the roof of the fort to highlight the detail. I will then add further washes and use some Forge World weathering powders to show a more used and worn look.
As for the walls of the fort, these I will wash, drybrush and weather, but not as heavy as the roof floor.
Still lots to do.
