Use two uploaded reference photos of a mother and daughter to create an elegant black-and-white fine art portrait. Show both people standing back-to-back with their shoulders and upper backs gently touching, forming a close and intimate composition. Both subjects should be shown from the upper body up, with their heads at a similar scale and height. Their faces should be turned slightly toward the camera, creating a soft three-quarter or near-front portrait angle. Both should have a gentle, natural smile with a calm, warm, emotionally connected expression. Emphasize their family resemblance, especially in facial structure, eyes, smile, cheek shape, and jawline, while still keeping each person clearly distinct. The daughter should appear slightly younger and the mother slightly older, but both should look graceful, natural, and harmonious together. Style the image as a minimalist studio portrait with a simple plain background, high-contrast black-and-white tones, soft directional lighting, subtle shadows, and a refined editorial photography feel. Clothing should be simple, dark, and non-distracting. Hair should look natural and neat. The final image should feel timeless, intimate, elegant, and emotionally warm, like a professional family portrait photographed for an editorial or fine art studio session. Realistic skin texture, clean composition, no text, no watermark, no interface elements, no extra objects.
