But subtle themes within spirituality are evident in her growth as an artist.  One of Koh’s early series, Ladies, reveals the tense character of human nature, while her recent works, Refuge and Eternal series, reflects a more tranquil state of mind.  This tranquil state of mind is Koh’s quest through her depiction of magnificent landscapes.

Koh’s popularity resonates from the consistent one-man shows that have been held in the same gallery in New York City for the past ten years; she plans to continue this tradition for years to come.  But Koh has also achieved wide popularity internationally and nationally with prestigious shows in various cities throughout Korea, China, Canada, France, and the United States.  Though heralded by many and various professional art critics, Koh’s greatest critical acclaim comes from her audience, who proclaims that Koh’s art instills within them a sense of tranquility.
