Cinematic Portrait Dissolving Smoke Effect

Create an ultra-realistic cinematic portrait of a young man standing on a rooftop at sunset, wearing a light grey t-shirt, beige cargo pants, white high-top sneakers, a wristwatch, and black sunglasses. The subject stands in a calm side profile pose with hands in pockets. A dramatic visual effect is applied where the left half of his body (from the viewer's perspective) dissolves into a swirling cloud of dark smoke and glowing orange embers, creating a disintegration or 'ash' effect that blends seamlessly into the warm, golden-hour lighting.
