In addition to her installations and sculptures with light, Park has an intensive drawing practice, which she likens to cross-genre or hybrid works. Siting Lucio Fontana and ZERO Group as key influences, Park punctures the surfaces of her drawings with holes and laser-cut incisions, exploring the objects' dimensionality, liminal space, and use of light as material. Light after all, is a central concern of Park's work, and when prompted about her process during Covid, she commented on a raised awareness of the light in her rural surroundings in West New Hampshire – the white flecks of road reflectors against a pitch-black curtain of night, specifically. In her Sequin Curtain drawings, Park experiments with retro-reflective, glass bead paint, as well as dichroic film, both of which create layers of visual experience.
"All of my work examines facets of perception. It challenges viewers who must discover how to perceive the form properly. Pieces that look two-dimensional have sculptural layers that create reflection, refraction, and what I like to call "inflection". They change, or inflect, one's perception. Understanding how these works can skew vision is central to understanding some ways that our everyday perceptions may be manipulated by inner or outer forms, interference and complexity. This understanding is aesthetically rewarding, leaving viewers with a renewed appreciation of perceptual possibilities, ways of looking at art, and ways of seeing." – Soo Sunny Park
