What can you say about the sky? When you felt down, stress, what would you do? Yes, look at the sky, then you’ll feel calm, more relax. Because the sky is something unpredictable. The pattern changes according to the weather, the movement of the wind. And the light-blue-background colour makes the sky looks simple and relaxing.
Have you ever think, what is the limit of the sky? Why is the sky never fall down even without any pile? What will happened to the air-traffic if the sky has piles?? For sure the sky is not beauty from what we have seen now!
