Photorealistic Equestrian Portrait Prompt

Create a photorealistic 9:16 vertical equestrian portrait of an exceptionally beautiful adult East Asian woman standing closely beside a large dark-bay horse in an open grassland riding field. She has an elegant oval face, luminous fair skin, dark almond-shaped eyes with refined winged eyeliner, softly arched eyebrows, a delicate straight nose and naturally full muted-red lips. She looks directly into the camera with a calm, composed and quietly confident expression. Her glossy black hair is swept away from her face and arranged in a neat low traditional updo, with subtle volume at the crown and a few fine natural strands around her temples. She wears small dark-red gemstone earrings, a pale jade bangle on one wrist, a pearl-and-jade bracelet on the other and a delicate gold chain bracelet. She has a tall, graceful hourglass figure with a full bust, narrow defined waist, softly rounded hips and elegant feminine proportions. Keep her body attractive but anatomically natural and believable. She wears an elegant ivory-white traditional Chinese and Mongolian-inspired equestrian dress made from softly lustrous silk brocade. The fitted top has a high mandarin collar, an asymmetrical overlapping front, delicate gold frog closures, three-quarter sleeves with folded cuffs. Subtle woven cloud patterns, circular auspicious motifs and pale-gold ornamental patterns cover the fabric. A wide structured ivory waistband emphasizes her waist, while the long pleated skirt falls smoothly toward the ground. Reproduce the pose: she stands upright on the left side, shoulders square to the camera, body close to the horse. One arm hangs naturally, her other hand holds the reins beneath the horse's muzzle, suggesting a trusting connection. The dark-bay horse stands beside her, head entering from the upper-right, facing forward with relaxed ears and a broad muzzle. Its coat is deep chocolate brown with natural highlights. The horse's neck, shoulder and saddle remain visible in the background. Preserve accurate equine anatomy and realistic scale. Background of a softly blurred riding field with muted green grass, reddish-brown earth, distant blue-gray mountains and pale blue sky. Only a subtle field element in the distance, keeping it uncluttered. Use a frontal eye-level camera angle, mild wide perspective, framing from head to below knees. Soft natural daylight on both. Slightly soft camera rendering, restrained color grading, natural depth of field and film grain. Detailed, photorealistic, natural face, accurate hands and horse. No text, no watermark.
