Greek / Roman ancient ruins. The main idea came as a video game environment style. I wanted it to look more realistic so I end up using GI and hi-res models. Even if I used hi-res models, I used lots of game techniques. I'm thinking about bringing this scene to UDK and CryEngine in the future.
I couldn't afford to add the waterfalls as intended, maybe later if I have some time to spend on RealFlow I'll be able to get the scene fully finished.
