Create an ultra-photorealistic cinematic

Create an ultra-photorealistic cinematic mirror-selfie portrait of a young adult East Asian woman in her early twenties, approximately 20 years old, standing confidently in a modern indoor changing area with cream-colored tiled walls, warm wooden architectural beams, and a rectangular skylight revealing a vivid blue sky. Capture the scene in a vertical composition, framing her from the top of her head to her upper thighs, with her body centered and the camera positioned at approximately waist-to-chest height, angled slightly upward. Recreate the casual, playful atmosphere of an authentic smartphone mirror photograph.

She has a delicate, softly rounded oval face, a gently tapered jawline, fair ivory skin with subtle warm undertones, and large, expressive dark brown almond-shaped eyes accentuated by subtle eyeliner and naturally defined eyelashes. Her nose and lips are concealed behind a fitted charcoal-gray face mask with a pronounced central seam. Her eyes convey a cheerful, slightly mischievous expression as she looks directly toward the mirror.

Her silky dark brown hair is styled with straight, wispy bangs falling across her forehead just above her eyebrows. The remaining hair is gathered into a long, slightly loose low ponytail resting over her shoulder and cascading diagonally across her chest.

She has a slender yet naturally curvaceous figure, a defined waist, softly rounded hips, and balanced feminine proportions. She wears a fitted, opaque ivory-white short-sleeved cropped T-shirt with a high round neckline, ending just below her bust and revealing her bare midriff and navel. Over the shirt, she wears an oversized, open-front, fluffy white cardigan featuring a soft, shaggy, textured fabric and loosely draped sleeves. Her lower outfit consists of snug heather-gray athletic boyshorts with narrow white piping around the curved leg openings and a broad light-gray elastic waistband displaying repeated black Calvin Klein lettering.

Her left arm hangs naturally beside her body, while her right arm is raised above shoulder level, elbow bent, holding a thin pale-pink strap from which a soft, dusty-rose fabric tote bag hangs vertically beside her torso. The cardigan sleeve bunches around her raised forearm, emphasizing its plush texture.

The background features horizontal off-white rectangular wall tiles, warm honey-colored structural timber, a recessed blue skylight overhead, and muted architectural details suggesting a contemporary indoor dressing space. Soft overhead ambient lighting creates gentle shadows beneath her chin, across the cardigan folds, and around her waist. Preserve realistic fabric tension, natural skin texture, subtle mirror reflections, and physically accurate anatomy.
