oh ehm gee!!! Double light sources!! I really like it i like the smoothness of the dark corners, and the roughness of the planet. In a hole this picture tells a story, could be different for everyone... but i see a planet in drought, fighting against each other for there different beliefs. kinda like.... they see the light sources as different gods and there trying to prove which one is the real one... Idk, i let my mind wander... sorry xD In all seriousness, this is a truly fantastic piece, i am glad to have seen it.
