Create a vivid, hyper-detailed futuristic city skyline at sunset, divided by a shimmering, wide river reflecting neon lights. The city features towering skyscrapers with sleek, glass-and-metal designs, glowing holographic billboards, and floating gardens. Flying vehicles (hovercars, drones, and sleek transports) zip through golden-orange twilight skies, leaving soft light trails. The river is bustling with futuristic boats and illuminated bridges. Warm sunset hues blend with deep purples and blues, casting dramatic shadows. Add dynamic energy with bustling streets below, solar-paneled rooftops, and subtle eco-friendly elements like vertical forests. Style: Ultra-realistic with cinematic lighting, vibrant colors, and a sense of awe-inspiring technological harmony.
