A serpentine dragon god coiling beneath the mirrored surface of a mountain lake. 2026 trade-cover trend: oversized structural typography, high-contrast palette, strong readability at thumbnail size. All cover text must be Japanese only; render the quoted title and author name in correct, complete Japanese characters. Book cover with title "龍神の棲む湖" and author name "藤堂蓮" rendered on the cover.. Workflow direction: Create the finished flat front-cover artwork itself, not a photograph or mockup of a physical book. The rectangular front cover must fill the entire output canvas edge to edge, viewed perfectly straight-on with the camera perpendicular to the artwork. Build a compelling genre-appropriate key image, readable title hierarchy, deliberately placed author name, short correctly rendered Chinese or English title text enclosed in quotation marks, strong silhouette at thumbnail size, and trim-safe breathing room for practical editorial use.
Style-specific direction:
Style: premium epic-fantasy book cover; painterly realism with restrained engraved details, never a generic game screenshot.
Subject: preserve the requested character, landmark, era, and story symbol; make one unmistakable focal idea.
Composition: portrait front-cover layout, strong silhouette in the lower third, expansive title-safe sky, readable at thumbnail size, trim-safe margins.
Lighting or Color: dramatic rim light and volumetric rays; deep jewel tones, controlled shadows, and one luminous accent.
Typography: render the exact quoted title once in ornate metallic serif capitals and the exact quoted author once in smaller spaced capitals; keep both crisp and correctly spelled.
Output format: flat front-cover artwork only, filling the canvas edge to edge and viewed perfectly straight-on; no physical book object, spine, pages, back cover, perspective, mockup, badge, logo, watermark, duplicated text, or unrelated symbols.. Avoid: physical book, 3D book, book mockup, product mockup, spine, pages, page e
