Startup Founder Urban Rooftop Headshot

Act as a Silicon Valley Editorial Photographer. Create a breathtaking, highly ambitious LinkedIn headshot specifically for a unicorn tech startup founder. The background must be a sprawling, deeply blurred [CITY_SKYLINE] viewed from the precipice of a towering skyscraper rooftop. The image must be captured during the exact [TIME_OF_DAY] (e.g., the bleeding edge of Blue Hour or a violent, fiery sunset). Attire: Expensive, minimalist [CLOTHING] (e.g., a dark designer hoodie or a sleek bomber jacket). Emotional Mood: The subject must radiate a visionary, aggressive, and world-conquering boldness. Technical constraints: Force a massive f/1.2 aperture to obliterate the city lights into massive, glowing orbs (bokeh), while keeping the subject's eyes in punishingly sharp focus.
