Secon part of the tutorial!
I left you yesterday with unpainted walls. First, i glued some more "patches", to give a more variety to the different pieces:

Then a black primer and a rough brown coat:

for the ground, brown - to - white drybrush, to give an excessive contrast (good with the grass, imho)

then, for the wood, drybrush (not too dry) with orange, mixed with brown

finished with some white, for the aging:

then, the grass, to give the complete nordic-style orkish architecture.

hope it will be usefull to all you!
