Create a warm festive greeting card photo, vertical portrait aspect ratio (4:5), soft white background. Two people sitting closely together, viewed from chest-up, black-and-white (monochrome) candid photography style, soft natural lighting, shallow depth of field, gentle warm glow. Person 1 (brother): seated on the left, wearing a simple light-colored kurta, looking down warmly at his wrist with a soft smile, sleeve rolled up, arm extended forward. Person 2 (sister): seated on the right, wearing a traditional embroidered outfit with earrings, long hair styled naturally, looking down at the same wrist, gentle joyful smile, holding a decorative rakhi (gold and blue beaded thread bracelet) and tying it onto the brother’s wrist. Both expressions: genuine, affectionate, candid — as if caught in a real emotional moment, not posed stiffly. Lighting: soft diffused daylight, slightly overexposed highlights, faded/glowing background, high-end greeting-card editorial photography style, fine film grain, ultra-realistic skin texture, 8K quality. IMPORTANT: Keep both faces exactly as shown in the uploaded reference photos — do not alter facial features, only adjust pose, expression softness, lighting, and clothing to match the scene.”
