A deep-space antenna array listening under twin auroras on an ice moon. 2026 trade-cover trend: oversized structural typography, high-contrast palette, strong readability at thumbnail size. All cover text must be English only. Book cover with title "The Long Signal" and author name "Ingrid Sato" 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 science-fiction book cover with cinematic speculative-world design, clearly technological rather than fantasy; polished cinematic digital painting, optionally carrying a restrained retro-pulp print texture.
Subject: preserve the requested explorer, machine, planet, and setting; use one scientifically coherent futuristic focal idea.
Composition: portrait front-cover layout, horizon-scale environment, strong lower-third silhouette, open title-safe upper field, thumbnail readability.
Lighting or Color: electric blue, white, and deep space black with one warm accent; controlled volumetric light and precise hard-surface detail.
Typography: render the exact quoted title once in tall geometric techno 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, medieval runes, magic portal, fantasy crystal, spine, pages, back cover, perspective, mockup, badge, logo, watermark, or duplicated text.. 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, fantasy crystal, medieval architecture, generic space collage, mockup, spine, watermark
