Create a science-fiction book cover featuring a lone human silhouette standing on a panoramic platform overlooking a vast futuristic city. Precision: the cityscape should combine organic curved architecture with high-tech structures, soft holographic lights, and distant aerial traffic. Style: semi-realistic digital illustration, clean lines, subtle textures, cinematic composition inspired by modern sci-fi films. Tonality: contemplative, mysterious, uplifting — evoke the sense of entering a new era. Ambient décor: glowing towers, suspended bridges, gentle mist, and a softly radiant sky with two distant moons. Plan: wide shot showing both the character and the horizon. Angle: slight low angle, giving a sense of scale and grandeur. Colors: harmonious palette of deep teal, gold highlights, soft purples, and atmospheric light blues. Positive formulation: emphasize elegance, clarity, balance, and visual depth. Do NOT include: visible faces, explicit violence, aliens, spaceships in foreground, cluttered compositions, retro or cartoonish styles, 19th-century aesthetics, text fragments or unwanted typography, or overly dark horror tones.
