The Stool and Black Horse Portrait

Use the attached reference image and keep the person’s face, facial features, and identity exactly the same — no changes to their appearance. Black-and-white fine-art portrait. The person sits on a simple wooden stool in the middle of a quiet open field, wearing an oversized black coat and dark trousers, elbows resting on the knees, head slightly lowered, looking at the camera with a calm stare. A tall black horse stands right behind them, its head turned toward the person. Overcast sky, soft diffused light, deep blacks and clean highlights, fine film grain. Sharp eyes, detailed skin and hair, visible fabric texture, crisp horse coat. Vertical 4:5, ultra HD, ultra-detailed. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
