The main subject in Sang Won Kim's artworks is definitely a pine tree. His trees reveal the chains of autocracy through weighed boughs, rather than lofty and green. A pine tree is not just object for painting, it's the object that personality is reflected. Also, a pine is  inseparable from Korean culture. It has symbolized holy and integrity, so that Korean people thought and praised this as a basic condition to live in the past. 
The artist always visits a forest and paints trees in the flesh, and this unique way of work means that he thinks a pine particularly beyond a material. A process of working in a site is a sort of ceremony to him to communicate with Mother Nature. And it is to make a difference with other artists' techniques. 
Mostly, purple and green colors fill his works and they provide fantasy and mystique. Plus, short, fast and repetitive  drawing leads his paintings to more unique and unusual style. His unique skill is from his studying to make his paintings rhythmical. 
His painting looks familiar, but is fresh and warm as well as harsh and unshaped. Therefore, for character and contents of his artworks, 'A pine in Korea' can be called by implication.
