A cinematic, hyper-realistic editorial portrait of a woman with long, dark, wavy hair, standing gracefully beside a horse bathed in warm, ethereal light. She is wearing an elegant off-the-shoulder white gown with soft draping, holding dark reins gently in her hands. The scene is drenched in a rich, golden-hour backlight that creates a luminous halo around her hair and the horse's mane, casting dramatic shadows and highlighting the fine texture of the fabric. The atmosphere is dreamy, majestic, and serene, captured with a shallow depth of field, high contrast, and a vintage 35mm film grain aesthetic.
