Cyberpunk Megastructure Rider

Create a dark cinematic science-fiction concept art scene in a vertical 4:5 frame. The viewpoint is low and centered, looking upward inside a colossal gothic-mechanical megastructure: 1 immense cylindrical central tower rises from the foreground into the distance, built from stacked industrial rings, armored platforms, pipes, ribs, vents, and black metal panels, with a bright vertical molten-orange energy core glowing through its center. Surround it with 2 towering side walls of dense futuristic city machinery, filled with tiny amber window lights and layered mechanical detail, forming a deep cathedral-like shaft. At the top, show 1 huge circular open aperture revealing a starry night sky and 1 pale crescent planet or moon partially visible behind the rim, creating a halo of cold white light. In the foreground on a grated metal platform, place exactly 2 main foreground subjects: 1 lone female cyberpunk rider, seen from behind, wearing a fitted black tactical outfit with red accents and a decorative emblem on the back, short dark hair, standing upright and gazing at the tower; and 1 aggressive futuristic black motorcycle parked to her left, low-slung with sharp aerodynamic armor, red glowing strips, and orange engine lights. Add 1 waist-high railing across the foreground with small industrial lamps, wet reflective metal flooring, subtle fog, drifting particles, sparks, and atmospheric haze. Use a dramatic scale contrast, symmetrical composition, ultra-detailed hard-surface design, dark gunmetal palette with warm amber-orange lighting and cold moon rim light, high contrast, volumetric lighting, realistic cinematic rendering, epic dystopian cyberpunk mood. Customize the main figure as {argument name="character description" default="a lone female cyberpunk rider with short dark hair"}, the vehicle as {argument name="vehicle type" default="an aggressive futuristic black motorcycle"}, the central structure as {argument name="tower type" default="a colossal cylindrical industrial tower with a glowing orange energy core"}, the setting mood as {argument name="atmosphere" default="dark, foggy, cinematic, dystopian"}, and the celestial object as {argument name="sky object" default="a pale crescent planet behind a circular aperture"}.
