It's coming on. Just deciding whether to add another 'glaze' to some of the stonework, to add a bit more variety - so far there's pale yellow and orange on top of the sand - thinking of adding something greyish. And then I'll need to glue in the doors, floors and shutters.
I ended up going back to the original paint scheme idea - paint it sand, then drybrush up to white - because I couldn't get the wash to work consistently and without really obvious brushstrokes. The drybrushing looks less patchy in real life - the photo seems to accentuate it somehow.
