Create an epic, futuristic cityscape at sunset, with skyscrapers made of glass and metal that reflect the vivid hues of the setting sun. In the foreground, depict a group of adventurers preparing for a journey, each with unique, high-tech gear and futuristic clothing. Behind them, include a sleek, hovering spaceship ready for takeoff, with a transparent cockpit revealing intricate controls and floating holographic displays. The city should be surrounded by lush, alien foliage and strange, bioluminescent plants that cast an ethereal glow. In the distance, a massive, ancient-looking structure looms, half-covered in ivy, hinting at a mysterious past. Add subtle details like distant flying vehicles, holographic advertisements, and a sense of vastness and wonder. Use a color palette that combines neon blues and purples with the warm oranges and reds of the sunset, creating a striking contrast.
