The earth is under the sky, humans are on the earth. Everything is same under the sky. I came from Seoul, South Korea. Seoul is one of the biggest cities in the world. Manhattan was a battlefield to me for the first time, even though I was born and raised in a big city. Nevertheless, I can feel nostalgia, when I see Manhattan from the outside of Manhattan. Civilization has rapidly developed in the past 100 years, and a lot of complications happen these days. But wealthy, power, ideology, religion, all meaningless under the sky. All cities that are symbols of human civilization, and no matter how big existence is, a city is just really a small thing under the sky. I hope people can feel nostalgia and calm through these images, and give up their greed at the same time. The NewYork series is a starting point for larger work.
