An ultra-high resolution 8K photorealistic portrait showcasing a subject enjoying a vibrant Diwali night with a sparkler. The outdoor urban setting at night provides a dynamic, softly blurred backdrop of city lights. The individual, dressed in modern festive attire, holds a lit sparkler, its golden shower casting ephemeral light. Crucially, the subject's face is evenly and brightly lit from an external soft light source, ensuring 0% shadow and preserving their exact facial identity from the reference photo. A spontaneous, natural mild smile captures the pure joy of the occasion. The medium shot, slightly wide, delivers a professional photoshoot aesthetic, with incredible detail, natural skin texture, and true-to-life colors that pop against the night, celebrating the festive spirit of Diwali.
