Edit the attached ID-style photo. Do not change the face at all: keep facial features, skin tone, face shape, expression and head position exactly as they are. Only make these changes: 1) replace the background with a flat, even [배경 색 (e.g. pure white)] with no gradient or shadow, 2) tidy a few flyaway hairs around the head outline, 3) [옷 정리 (e.g. straighten the shirt collar and remove lint from the jacket)]. Keep the same framing, size and resolution.
