Ultra-high resolution 8K photorealistic portrait of a single subject, full body, during a traditional Diwali celebration. The subject is gently kneeling at a beautifully decorated home entrance, lighting an earthen diya. Preserve the exact facial structure, proportions, and identity from the reference photo, with the face evenly and brightly lit, displaying zero shadows or dark areas. A natural, mild-to-moderate smile perfectly captures the festive spirit. The subject wears an elegant silk saree in a deep marigold hue, adorned with intricate gold embroidery. Warm, soft glow from numerous lit diyas creates a magical golden hour effect, providing realistic lighting and shadow falloff everywhere except the perfectly illuminated face. The background shows blurred festive Diwali decorations. Professional photoshoot quality, true-to-life color grading, natural skin texture, no cartoon, illustration, CGI, or stylized look.
