Baek Min-soo was also featured by the same guys, 더스토리 TheStory last year. They featured his amazing Gundam works out of wooden chop-sticks.
He would leave the models unpainted to preserve its quality and concept.
Each of his works are really amazing and worth preserving. A real product of art!
You can see more of his works on his blog. [https://blog.naver.com/mindol100]
