치비 3D 피규어 FACS 표정 수정

Using the reference photo as the character base, keep the same chibi 3D figure, outfit, hairstyle, lighting, plain white background, and overall composition exactly unchanged. Modify only the facial expression according to FACS action units: [AU1C + AU2C + AU5D + AU26C]. Preserve the reference image's square face-obscuring block in the same central position, regenerating the image cleanly with the same toy-like 3D render quality.
