Ultra-realistic mobile phone selfie portrait of a young East Asian woman, maintaining a high degree of similarity to the reference face: soft oval face, slender jaw, natural narrow nose bridge, thin lips, true eye distance, calm and natural expression, retaining skin texture, pores and slight facial asymmetry, without any beautification or stylization treatment.

Sitting by the window indoors, bright natural sunlight streams in through the right window. A close-up three-quarter profile view, slightly looking out of the window, with a calm and relaxed expression. Long blackish-brown hair naturally falls over the shoulders, slightly disheveled, with fine, scattered strands visible in the sunlight. Wear large round black plastic-framed glasses. Naked body.

The intense lateral sunlight forms a high-contrast light and shade relationship, and the shadows of the window frame are slanted and projected onto the face and arms. True skin tone, subsurface scattering, slight oiliness and natural tone changes, no HDR overprocessing.

Minimalist background: Light-colored walls and window frames, no decorative elements, creating a quiet and natural indoor atmosphere.

Real smartphone front selfie effect: 9:16 vertical composition, visible when the arm is extended, slight wide-angle distortion, shallow depth of field but in line with the characteristics of a phone lens, real digital noise, lens softening and natural contrast. The main subject is located slightly to the left of the picture, with the edge of the window visible on the right. It is tightly cropped to the upper body. Key points to emphasize: authentic skin texture, natural optical defects, correct human body structure, real lighting behavior, no CG feel, no movie color grading, no excessive sharpening, no internet-famous filters.
