Thanks, Martin, I saw that thread indeed and did some renders trying it out. But as usual, I build up scenes and forget to incorporate a whole lot of interesting ideas, that I know in the back of my head, but that don't come out at the right time. I'll try this one with the village.
Springs to mind Chris Hunt's wonderful demo reel, where the final image of the dying dinosaurs have a great lighting. The darkness under their bodies is what I try to achieve with buildings, for instance. These are often too light inside.
