Managed some more work on my first building. Gave the whole thing a black undercoat, including the inside, then dry brushed with burnt umber. Once that was all dried I gave the whole thing a dry brush in cream to weather the building. Quite happy with the results.

Next up I just have to add some texture to the base and I can start on a second building. I've got a spare cart wheel that I might add to the front.
