A high-altitude view of a glowing, circular futuristic cyberpunk city on an island at dusk, with neon lights and a bioluminescent ocean.

A futuristic cyberpunk island city named Avalon, viewed from high altitude, showcasing the full oval-shaped city surrounded by a glowing alien ocean. The city is divided into 15 glowing neon sectors, with a dense layout of tall high-rises, glowing signs, and a web of illuminated SkyRail tracks converging on a large central depot. Sector 15 appears dark, ruined, and overgrown from an old EMP blast. Key landmarks include a power plant with eel tanks in Sector 13, a hospital-science complex in Sector 9, massive filtration towers in Sector 14, and high-class residential towers in Sector 1. Traditional architecture like pagoda rooftops blend with modern neon tech. The SkyRail connects each sector, visibly curving through the city like spokes from Sector 8. The atmosphere shows a vivid dusk sky with purple-orange clouds, 2 alien moons, and faint constellations. The surrounding ocean glows faintly with bioluminescent life, and subtle shapes of aquatic monsters can be seen in the water. A faint protective wall encircles the city, and distant islands or wreckage add mystery. Above, satellites or faint orbital rings hint at more technology in orbit. The style is highly detailed, semi-realistic, colorful, and cinematic — like a poster or movie concept art. See more
