This is based on the existing rice terraces in the Philippines. Since most rice terraces is built on a hill with a valley below it, I manage to conceptualize a huge valley that is surrounded by large terrace upon terrace of rice. Some parts of course are exagerrated but it would be really amazing if you can see this type of man made mega structure!

I used Maya to model most of the mountains and rocks which where then taken to Zbrush for refinement and then to Photohop for the final composition. The sketch is doen in Photoshop only.
