Ultra-realistic 4K cinematic portrait of a romantic couple celebrating Diwali, standing close together and looking straight into the camera with joyful, warm smiles. The couple is holding sparklers in their hands, creating glowing heart-shaped golden light trails in the air. Their faces are softly illuminated by the sparkler glow and surrounding Diwali lights — bright, radiant, and cinematic. The background shows a colorful festive Indian street decorated with Diwali diyas, hanging fairy lights, lanterns, rangoli, and glowing lamps — with dreamy bokeh and warm tones. They wear vibrant traditional festive clothes — the man in a royal blue or maroon kurta, and the woman in a red or golden lehenga or saree with shimmering embroidery. Add soft rim light around their hair and shoulders, cinematic color grading (gold, pink, and teal tones), and realistic HDR lighting. Camera style: Sony Alpha FX3 / Canon R5, 85mm f/1.4 lens, shallow depth of field, ultra-detailed skin texture, perfect lighting balance, 4K HDR cinem
