夜店旋转楼梯俯视肖像

Create a vertical cinematic nightclub portrait of {argument name="main subject" default="a confident young man"} standing still in the center of a luxurious spiral staircase, photographed from a dramatic overhead top-down surveillance-balcony angle. The subject wears {argument name="outfit" default="an all-black tailored suit over a black turtleneck"}, has neatly styled dark hair, one hand in his trouser pocket, and the other hand raised in a subtle finger-gun gesture toward the camera. Surround him with exactly 4 blurred clubgoers moving on the stairs: one at lower left in a light shirt, one dark-clad figure at lower center, one woman at right in a black dress, and one partially visible blurred figure at the bottom edge. The staircase is glossy black metal with curved railings, mirrored panels, and sharp geometric blue and violet LED light strips tracing the rails and walls. Add dense white-blue smoke or fog rising behind the subject, dark paneled walls with gold trim, reflections on polished surfaces, and a moody luxury club atmosphere. Use high-contrast cinematic lighting in {argument name="neon color palette" default="electric blue, violet, magenta, and deep black"}, shallow motion blur on the surrounding people, crisp focus on the central subject, wide-angle perspective, vertical 9:16 composition, realistic photography, no text, no watermark.
