Act as a visionary concept artist with 10+ years of experience in sci-fi worldbuilding. Create a highly detailed, cinematic Stable Diffusion prompt for a futuristic cityscape at sunset, featuring [flying cars in sleek, aerodynamic designs], [neon lights reflecting off towering skyscrapers], and [holographic advertisements floating in the air]. The scene should evoke a sense of advanced technology and vibrant urban life, with a warm, golden sunset casting long shadows and enhancing the neon glow. Include subtle details like [crowds of diverse futuristic citizens] walking along elevated walkways, [drones delivering packages] between buildings, and [lush vertical gardens] integrated into the architecture. Use a color palette dominated by deep purples, electric blues, and fiery oranges, with a focus on dramatic lighting and atmospheric perspective.
