Quite varied actually. I have done outerspace, alien environments, or just futuristic earth environments, such as those found in RIFTS (a RPG that I run in RL if you don't know what it is). Also, I would like to create something realistic and/or believable for backdrops in DV films I am working on, multiple genres, but it's not always feasible to film on location, so I am hoping to find something that will make "photorealistic" backgrounds when I can't.
