プロンプト
Create one finished epic fantasy front book cover in a single generation, 1024:1536 portrait composition, flat cover artwork only, never a book mockup. Exact title text: "THE LAST WYVERN". Exact author text: "SERA QUILL". Subject: a weathered dragon circling a snowbound watchtower at dawn. Composition: preserve a clean title zone, one dominant focal idea, readable silhouette at thumbnail size, and professional trade-publishing hierarchy. Style: cinematic painterly realism, monumental scale, atmospheric depth, one strong silhouette. Color and light: jewel-tone indigo, ember gold, and weathered stone. Typography: ornate engraved serif capitals with restrained metallic highlights; render the exact title and author once only, with correct spelling, clean kerning, no extra words, no duplicate letters, and no invented publisher marks. Constraints: print-ready front cover, polished visual hierarchy, coherent anatomy and perspective. Avoid: malformed text, repeated author names, extra logos, watermarks, borders, 3D books, hands holding a book, or horizontal mockups.
