I can see the pub from here

Well, maybe not the pub, but possibly the end of this project. On a side note, I have actually been to the pub from the XXXX advert, it's in Oz, it's very cool and has (well had 14 years ago) a car from Mad Max 2 parked outside. I spent two weeks out there once (field work, not in the pub) and brought my wife (then fiancee) a stubby (beer bottle) holder, themed shot glass and a fridge magnet back as gifts (from a major silver mining region). And she still married me, bless her.

I took the plunge and glued the buildings down. They've had various washes with Agrax Earthshade over the browns and in some of the cracks and several washes of the water from the brush pot which sounds terrible but gives a really good dusty/dirty look to the surfaces with the same pigments I've used for the base and the buildings. So they look a little better.
I'm still working on the surface colours too but now I've got the buildings down it will force me to be more careful and think about whether I need to keep adding colour. Or I'll be here forever.

Also, any surfaces I think are too shiny or uniform have had a few wash coats to "knock back" the shine and produce some variation.
So, this "aerial" shot, again produced in partnership with being too short and teaching your children some new swear words because you didn't know they were in ear-shot, shows where I am now 

I'm still not happy with the surface colour in places, too orangey/green and the buildings need to be "blended in" to their surroundings. That means (for me) adding textures to the edges of the buildings so there are no gaps and they look like dust and sand has accumulated around the edges.

I also need to start thinking about finishing up with accessories, some sparse vegetation, scrubby trees, some discarded equipment and a couple of road signs I think. For the trees I've got some bits of privet drying out in the oven, that's not a phrase I've used before, it'd make a great euphemism for something - "I'm just drying out me privet in the oven".
