Oh is an artist of fine arts who loves forests, traveling, and engaging in deep contemplation. She writes under the pseudonym Onjung, representing an open mind and warmth of soul. For Oh, illustrating is a form of rest from writing, while writing is a welcome break from illustrating. While in art school, she went on an unexpected journey where she discovered the joys of sketching during her travels. She later went on to found the online social club Art and People. With the community she has started through the site, who are fond of drawing and who see themselves as her “pupils,” Oh has been sharing her philosophies on travel sketching and lessons from their lives for the past fifteen years. Oh constantly searches for ways to contribute to society through her talents, with one of these results culminating in the Start Today series. As always, she hopes to continue to remain an artist with a positive attitude, who sees the world clearly and translates that to her pages. Her publications include Start Drawing Today, Start Travel Sketching Today, Start Animal Drawing Today, Unnecessarily Blank, Drawing Workbook for Today, THE CATS, and Don’t Cry Animals!​
