Create an emotional yet natural and highly photorealistic portrait of an Indian brother and sister sharing a heartfelt Raksha Bandhan moment. The sister wears a sophisticated dusty-rose ethnic suit with gold detailing, a matching dupatta, traditional earrings, bangles, and a small bindi. Her brother wears a classic ivory kurta with delicate gold embroidery and white pajama trousers. Position them seated together on a traditional wooden sofa after the sister has tied a beautifully handcrafted rakhi around his wrist. The sister gently holds his wrist while both turn toward the camera with warm, genuine smiles that convey affection and sibling closeness. Their faces must be completely unobstructed, clearly visible, sharply focused, and evenly illuminated using bright soft frontal portrait lighting with warm fill illumination. Decorate the background with dense marigold garlands, warm fairy lights, glowing brass diyas, fresh flowers, traditional artwork, and a tasteful “Happy Raksha Bandhan” sign. Place a richly decorated thali in the foreground containing kumkum, rice, rose petals, laddoos, barfi, diya, and additional rakhi threads. Keep wrapped gifts naturally arranged on the floor beside them rather than in their hands. Preserve realistic Indian skin texture, natural facial proportions, detailed hair strands, authentic ethnic clothing, embroidery, jewelry, accurate hands and fingers, realistic sweets, flowers, metallic surfaces, and diya flames. Capture with an 85mm professional portrait lens, shallow depth of field, creamy cinematic bokeh, warm realistic color grading, and premium Indian festival portrait photography. Ultra-photorealistic 8K, vertical 4:5 composition, no cartoon, no CGI, no plastic skin.
