Today I have a GW-style tournament board that I painted up over the holiday period. I managed to get a good bargain on ebay for the old Sector Imperialis terrain, so was able to build up a GW-style tournament board for my gaming club and tournaments.
I already have a set of ruins painted up in a desert style, red and green terrain, so decided to go with blue for these. I went a bit more in depth with these ruins, painting the windows in gold, as well as adding in some red for the lights and control panels.
I used a similar scheme to the Boarding Actions terrain that I painted up, and was really happy with how they turned out.
