Pushing the possibilities of urban imagery, Choi is interested in giving shape to the fleeting impressions of a city through interweaving fragments of memory in her paintings and videos. Her creative process is like searching for light under overcast skies. The landscapes she paints often remind us of humanity’s insignificance through juxtaposing the visible and the invisible, the artificial and the natural, the scattered and the gathered, micro and macro beings; their coexistence reflects the artist's state of mind. If a painting is a manifestation of infinite borrowed space and time, Choi attempts to negotiate the gap between the tangible and the intangible, and to explore indescribable space and time with the light of hope and the power of urban imagery. In recent years, Choi has familiarised herself with wood and explores the definition of freedom with multi-perspective and layered temporalities, imbuing the material with her state of mind through the repetitive processes of preserving, sanding, washing, and sprinkling.
