论文没写完，但这张脸先自拍了

Resting her right cheek gently against the back of her hand, fingers lightly curled near her face in a relaxed, contemplative pose with her head tilted slightly to the side, a young East Asian woman in her early 20s appears in a realistic close-up portrait. Fair, smooth skin frames delicate features — large expressive dark brown eyes with long natural lashes and subtle eyeliner, softly arched brows, a small straight nose, and full soft pink lips slightly parted in a calm, neutral expression. Long, slightly wavy dark brown-black hair cascades over her shoulders, partially framing her face with soft volume and natural texture; she wears a simple black long-sleeve top or hoodie. Soft indoor lighting lays gentle highlights on skin and hair in a warm neutral tone, against a slightly out-of-focus dark brown leather or fabric couch. Photorealistic style, richly detailed skin texture, hair strands and facial features, natural makeup (subtle blush, glossy lips), shallow depth of field, an intimate selfie-like composition, soft cinematic lighting.
