Here's an image I'm working on on and off.
Concept: In the future the human face ran out of viable space on the surface of the planet they build huge platforms to have a second layer of real estate. As time progressed into the future, the disparity between rich and poor became wider and wider. The middle class working men has been completely eliminated as a result. The structures underneath this platform would be for poor people who cannot afford to live on the top where there are sun light. Only the extreme wealthy have the money to facilitate living on the surface of the structure.
On the technical side, I'm trying out some new things I've learned from James Paik's environment design class. It's a real eye opener to check out his demos.
