Mechanical bird flying through a dystopian mega-city

A hyper-realistic cinematic AI-generated video of a sleek mechanical bird flying at high speed through a vast futuristic post-apocalyptic mega city at dusk. The machine bird has a metallic body with intricate articulated wings, glowing bright blue neon accents, visible spinning gears, pulsing lights, and detailed mechanical joints. Dynamic fluid camera follows the bird in immersive first-person POV style with slight fisheye lens distortion, smoothly weaving between crumbling towering skyscrapers covered in overgrown vegetation, exposed wiring, and rust. The bird glides over rooftops, dives through narrow dark alleyways, and soars across the sprawling desolate cityscape filled with flickering holographic billboards and scattered debris. Moody dystopian atmosphere with a muted color palette of grays, rusty oranges, dark tones, and vibrant neon blue highlights. Dim cinematic lighting suggesting twilight, with soft volumetric god rays, subtle mist, and occasional flashes from artificial lights. Fast-paced yet smooth motion with a strong sense of speed, freedom, and scale. Ultra-detailed textures on both the mechanical bird and decaying architecture, sharp reflections, film grain, shallow depth of field, and dramatic sci-fi aesthetic blending Blade Runner and post-apocalyptic themes. 8K resolution, hyper-realistic CGI, no text or people visible.
