Hehe there might be some savages - helmets and axes wouldn't be that far out. But remember - vikings didn't have horns on their helmets... sadly!
I'm a bit in doubt about the paint-side of things. I wan't it to look battered and unkept. I'm thinking that the wall will be offwhite (with lots of smothering on them) and perhaps some algae. The roof should be grey/black I think, with a lot of green washes to simulate algae.
The grounds around the house should be unkept and covered with debris, grass tuffs, bones and a car wreck or similar.
I'm just starting 20mm sci-fi but I can't wait to get going! I have quite a lot of 20mm/1:72 Vietnam War already.
My big hope is to land a italeri B52-g and crashland it and turn it into a bar.
