Seoul 2150: River of Light

Cinematic 3D render, horizontal 16:9 desktop wallpaper, the future Seoul skyline of 2150 across a wide dark river at night, viewed from an elevated panoramic vantage. Foreground: the broad river surface in deep midnight blue, broken into shimmering reflections of neon and tower light, a sleek maglev bridge crossing low in the frame with a train rendered as a smooth streak of white and cyan light, and the dark silhouette of a near embankment with a row of small glowing lanterns. Midground: dense clusters of arcology towers rising from both banks, dark alloy and glass megastructures with terraced gardens glowing faintly green, thousands of tiny warm and cool window lights, holographic sky signage in abstract glyphs and geometric shapes in magenta and cyan floating between towers, and streams of drone traffic drawing curved light trails at several altitudes. Background: a second taller bridge fading into blue haze, a thin orbital ring station arc visible high in the sky with blinking markers, low clouds catching city glow from below, and a deep indigo sky with faint stars near the top edge. Composition uses the river as a strong leading line from the lower left toward the tower cluster center-right, camera at a 24mm wide lens with deep focus so foreground reflections and distant towers stay readable. Lighting is a deep blue night base with magenta neon bounce on the left bank and cyan accents on the right, volumetric haze softening the far towers, light behaving realistically on wet water, glass facades and brushed alloy. Materials feel premium: dark glass, wet stone embankments, glowing holo panels with refracted edges. Style anchors: Unreal Engine 5 cinematic render, octane lighting, blockbuster sci-fi cityscape, wallpaper-grade layered depth.
