Create a vibrant line art illustration of a futuristic cityscape at dusk. Towering skyscrapers with neon-lit facades stretch towards the horizon, while sleek cars and hovercraft zip through the streets. In the foreground, a lone figure in a sleek jumpsuit stands atop a building, looking out upon the metropolis. Softly lit clouds gather in the sky, casting a warm glow on the city's steel and glass towers.
