That is beautiful color choice I must say due to selection of cold on right and warm colors on left that made me to think about two world, where day and night separated with thin wall of invisible power that these two world never connect to each other and even may be do not know about their own existence. In the middle because of that merge there is no gravity that makes the stone to float both sides can see it and that is the point where they gather on both sides even sometimes the same time but they never see each other, though they feel that energy of presence of others and this magic and not explainable feeling brings people to that middle point.
