Candid Candlelit Restaurant Portrait

[Subject description] Fictional adult East Asian woman, age 20, with the fresh, energetic air of a college student, clearly an adult; height 185cm, long legs, full and athletic build, full bust, slim waist, toned hips and thighs, naturally pronounced hourglass curves, natural proportions; softly shaped oval face with slightly rounded cheeks, clear, bright almond-shaped eyes that curve into crescents when she smiles, naturally straight brows, hydrated pale-pink lips, very light makeup; long black hair in loose waves over her shoulders, with a small bright orange hair clip on one side; fitted, short-sleeved royal-blue off-the-shoulder top (snug stretch ribbed fabric), black high-waisted tight yoga pants fitted to the ankles (not flared), glossy bright orange pointed-toe kitten heels; no jacket indoors, and no jacket draped over her shoulders.
[Scene and action] An upscale restaurant at night, with warm candlelight; a candid moment as she has just picked up the sparkling water in her stemmed glass and bursts out laughing at a joke from a friend across from her, looking to the side and off camera, not at the lens; a city nightscape beyond the floor-to-ceiling window and blurred dining tables behind her.
[Visual style] Casual iPhone snapshot.
[Composition and camera] Vertical 2:3, medium shot from the knees up, eye-level camera, subject on the left third, with about 40% on the right left for the floor-to-ceiling window and nightscape; 35mm, f/1.8, subtle film grain.
[Lighting and color] Candlelight on the table and warm pendant lights shine from the front side, with soft diffusion and a rim of light around her hair; bright areas on the face are clear, with delicate layers of shadow; cool blue night outside the window for contrast; main colors are royal blue and black, accented with bright orange; color temperature around 3800K, natural, luminous skin tone.
[Material details] Real pores, fine facial hair, natural highlights, a faint blush on the cheeks, slight asymmetry between the left and right sides of the face, reflections in the eyes, fine lines on the lips, individually defined brows, natural-looking light makeup; stretchy ribbed texture on the short-sleeved top, subtle wrinkles in the matte yoga pants, glossy reflections on the kitten heels; fine hair strands and flyaways; reflections in the glass, tabletop reflections, and candlelight shadows.
[Negative constraints] Plastic skin, doll-like face, influencer face, excessive skin smoothing, beauty filters, heavy makeup, 3D-rendered look, distorted features, extra fingers, awkward limbs, floating subject, color cast, text, watermark, jacket, jacket draped over shoulders.
