Capture a vibrant, photorealistic portrait of a female subject, celebrating Diwali, kneeling gracefully on an open, paved patio, joyfully watching a spinning 'chakkri' (ground spinner firework). The night sky is dark, providing a stark contrast to the dazzling, colorful sparks emanating from the firework. She is wearing a modern yet festive vibrant yellow lehenga choli, her hair gently swept back. Her expression is one of pure exhilaration and amusement, a natural, mild-to-moderate smile reflecting the excitement of Diwali. The background is blurred with distant urban lights and faint Diwali decorations. The image needs to be ultra-high resolution, 8K quality, with impeccable focus on her face, showcasing natural skin texture and the dynamic play of light. Her face must be evenly and brightly lit, with absolutely zero shadows or dark areas, rigorously preserving the exact facial structure, proportions, and identity from the reference photo (same face shape, eye spacing, nose, jawline, skin tone). Lighting is a dramatic interplay of the intense, dynamic light from the chakkri, augmented by a constant, soft, high-power fill light directed at her face. True-to-life color grading, free from any cartoon, illustration, CGI, or stylized/plastic appearance, creating a visually stunning, high-end lifestyle shot.
