Actually that is rather helpful. I was thinking of using some of the more vibrant fake aquatic plants to mesh into the death world stuff. Using the oval shaped bases on the jetbikes is an interesting idea too, fixes some of the stability issues on uneven boards and gives you more room to play with for the basing.
Has anyone gone with non-earthy coloured ground? Even the mars style red-ish toned soil feels a bit too close to home
