A masterpiece, best-quality, ultra-detailed surreal sci-fi–fantasy illustration blending SCI-FI × Ancient Egypt × Railway Fusion with minimalist flat design, pastel colors, watercolor and impasto accents, cinematic lighting, and dynamic composition (artists: quasarcake:0.6, Yamamoto Souichirou:0.8, hungry clicker:0.6). A light-blue-haired girl with short hair and light-blue eyes, perfect anatomy and anatomically correct hands, wearing a mechanical white hazmat suit with mechanical arms, black high-heel mechanical legs, a white animal helmet with mechanical eyes, and a light-brown load-bearing vest, riding a snowmobile with huge backrest over a snowboard while holding a white musket, surrounded by aurora effects and futuristic glowing cyberpunk railway tracks in a snow mountain night scene with volumetric fog, neon signboards, and epic perspective (from above, from side, or three-quarter view). A small glowing pastel-pink fur cat rides beside her. Mummy Queen fusion elements: elegant wet-effect loose bandages, long hair, red pupils, mummy cartoon hair clip, pure white skin, ancient Egyptian tattoos, golden mummy coffin, naughty leaning pose hugging a large sword with shining Egyptian carvings. Scene expands into surreal pharaoh pyramid ruins blended with a sci-fi railway dimension, with phantom mummy ghosts, chibi mummy devils, haunting atmosphere, dynamic action, freestyle movement, intricate energy, parallel-dimension surrealism. Additional surrealist layer: close-up of a young woman's head emerging from calm opaque pink water, the top half replaced by a large furry black cat head with luminous green eyes; gentle circular ripples and dark distorted reflection on flat pink background. Also included: a ghost queen standing on skull ruins under blood-moon rim lighting, sword planted into ground, head slightly tilted, glowing skull-shaped pupils (cute yet eerie), regal gothic armor, flowing black-silver gown, mist and embers, ghostly fog, intimidating elegance. Finally, an 8K ultra-detailed mecha girl with full-body machinery, mechanical legs, mechanical rabbit ears, black long hime-cut hair, sailor uniform, raising a sci-fi katana in a dynamic side half-squat pose amid volumetric rain and wind-tossed hair, accompanied by a flying rabbit drone. Entire artwork emphasizes bright color, sharp focus, ray tracing, depth of field, high contrast, dramatic shadows, harmonious composition, dignified yet intimidating aura, absurdness, very aesthetic tone, perfect proportions, strong presence, expressive surreal energy (score_9, score_8_up, masterpiece:1.2).
