An astronomer-mage reading a constellation through a brass telescope atop a vine-wrapped tower. 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 "星読りの塔" and author name "藤宮律" 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 one compelling genre-appropriate key image on a single strong subject in a single scene — never a collage of competing motifs. Follow the 2026 trade-cover direction: oversized structural title typography treated as part of the artwork, a high-contrast palette, an author name placed deliberately and secondary to the title, short correctly rendered title text in the requested language enclosed in quotation marks, and a silhouette that stays readable at 100-pixel thumbnail size in a two-second scroll, all with trim-safe breathing room.
Style-specific direction:
Style: premium fantasy or romantasy book cover; painterly realism with restrained engraved detail and delicate ornamental motifs, the title lettering itself treated as artwork in the 2026 romantasy manner; 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, one luminous accent, and a subtle metallic-foil gleam on ornament and lettering.
Typography: render the exact quoted title once as oversized ornate serif capitals with an engraved or foil-stamped flourish; render 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 edges, back cover, perspective view, angled cover, tabletop, pedestal, hands holding a book, room scene, drop shadow around the cover, misspelled title, crowded typography, weak focal point, busy collage of competing motifs, washed-out low contrast, text too close to edges, unrelated imagery, garbled author name, misspelled or duplicated title, misspelled author, modern city, game UI, crowded typography, text near trim, mockup, spine, watermark
