New York across two centuries cinematic poster

Create a cinematic 3:4 vertical poster of New York City that feels truly epic and unconventional, showing the passage from the 20th century to the 21st century in one seamless image. Place a lone figure at the center of the composition, standing in the middle of the street and looking forward as if witnessing New York across time. The left side should depict 20th-century New York with warm sepia atmosphere, vintage taxis, old newsstands, retro lamps, and landmarks like the Chrysler Building and Empire State Building. The right side should depict 21st-century New York with glass skyscrapers, One World Trade Center, digital billboards, and modern urban energy. Make the transition natural rather than split-screen, with coherent perspective, wet reflective pavement, realistic textures, atmospheric depth, and no text.
