Silver-haired warrior girl holds a giant mechanical sword inside a ruined gothic cathedral with industrial elements

Prompt

Create a tall vertical dark-fantasy anime illustration of an unnamed silver-haired warrior girl inside a ruined gothic cathedral fused with industrial machinery. The composition is an extreme low-angle heroic portrait: one young woman fills the lower two thirds of the frame, twisting her body upward while holding one colossal mechanical greatsword vertically above her head, its blade extending to the top edge like a cathedral spire. The weapon is a single oversized steampunk sword with a glowing orange energy core running down the center, exposed pistons, layered metal ribs, circular gears, bolts, pipes, and vents releasing white steam on both sides. The character has long silver-white hair, pale skin, sharp sleepy eyes, and a calm, slightly melancholic expression; her hair streams outward in many flowing strands as if caught in wind. She wears a tattered black-and-white gothic battle dress with torn ruffles, lace, straps, asymmetrical armored sleeves, thigh armor, belts, and metal gauntlets, mixing elegant lolita frills with heavy mechanical armor. Add several long white ribbon-like cloth strips trailing around her body, but keep them as fabric motion accents rather than extra characters. The background is a towering, shadowy cathedral interior with broken arches, hanging chains, scaffolding-like ribs, smoke, dust, faint backlight through damaged windows, and a sense of immense vertical scale. Use a muted palette of charcoal black, ash gray, bone white, tarnished steel, and subtle copper-orange glow from the sword. Style should be highly detailed Japanese anime concept art with painterly rendering, dramatic chiaroscuro, intricate linework, cinematic atmosphere, vertical 9:16 crop, no text, no watermark, no border, no extra people, and focus on the single warrior and her single gigantic illuminated blade.
