Yelin Lee expresses the gap between childhood and adulthood through portraits of girls who looks like a character in cartoons. Based on digital works, she has released acrylic paintings recently and is loved by many collectors. She conveys the theme only with the girl's close-up face and gazes with the monotonous background. What is interesting is that the subtle expression of the girl and the clear color make us imagine our childhood. In particular, works with the color blue have become so popular that the term "Yelin ‘s Blue" was coined. She has started working not only on digital, but also on original paintings, and more recently on NFT. So it is looking forward to her activities in the future.
