While living with nature, the "Flying the Sky" series was created by using the natural tree-shaped and colorful shapes of branches as much as possible to create children's images using their legs, arms and heads. While producing only the figures, he came to think of a shepherd like a puppet from the Joseon Dynasty and transformed it into a modern style and began to paint. The writer's heart is that he wants visitors to experience the experience of wandering through space for a while in a strange optical illusion while watching various images of children reacting to the breeze.
