Ah, thanks chaps. Your encouragement inspires me to further efforts!

This morning I sprayed the whole caboodle with an earthy brown, and gradually lightened this with small additions of cream colour paint to the mix, so that, believe it or not, I overlaid 6 coats.
The end result is a bit hard to see from the pics, but I like it - it's a lot more subtle than good old drybrushing, gives a nice even finish, and a realistically dusty look.
Obviously, if it was going to be desert, that'd be the job pretty much done!
As it is, I now need to repaint all the detail - cliffs, fences, logs, stumps, walls, river, trackways etc - then get to work greening the whole thing up and deciding where the hell I'm going to insert all the trees that will miraculously transform the scene from a post-apocalyptic dustbowl to a verdant North American forest...

Hmmm...
