Another 15 minutes in the coffeeshop gave me this iPad doodle. I want to work more with industrial shapes and latticework towers. I see a lot of it in my neighborhood since there is so much construction, including a "skyway" for the Metro line to Reston and Dulles airport. But for that "concept art environment" look it has to be less abstract and more "realistic" even if it is fantasy. Fantasy can do an anti-gravity structure but it has to look as though it had mass and light could reflect off it. I will not spill milky coffee on my iPad, even in Earth-normal gravity.
