Use case: illustration-story.
Create ONE original literary cover illustration. Portrait 2:3, 1024 by 1536 preferred, flat edge-to-edge paper. No book mockup.
Art direction: quiet mid-century printmaking, irregular ink edges, fine restrained natural paper grain, matte warm ivory (#f1ede3). No more than two main muted ink colours plus graphite linework and the ivory paper. Wide, confident forms; very few small details. A lived-in spatial scene with a sense of distance, weather or absence—not a floating icon, logo, object sticker, or decorative emblem.
Reserve the entire top 43% as completely empty warm ivory for separate live typography. The narrative occupies roughly 47%–87% of the canvas; the bottom 9% remains clean ivory for an author line. The scene can reach the side edges. Coherent at 180 pixels wide. Paper is the light, not a bright sun.
No text, letterlike marks, digits, signature, watermark, publisher logo, frame, collage, glossy 3D, photorealism, cute cartoon, ornate ornament, heavy distressed texture or green. Make an original interpretation, not a copy of any published cover.

Work: The Old Man and the Sea by Ernest Hemingway. Emotional tension: human smallness, unbroken resolve. Two very broad curving deep muted-blue shapes make a vast sea. An extremely small pale ivory skiff with a tiny warm-copper edge sits almost lost in the sweep of water, a fine broken fishing line descends into a darker deep-blue shape. The ocean's scale and the boat's smallness must be instantly felt. Broad empty ivory above the water; an expansive horizontal scene occupying the lower half. Only three or four thin cream ripple lines. No visible person or face, no giant fish illustration, no birds, no sun, no star, no coastline, no fishing-gear still life. Palette: desaturated midnight blue and a single tiny copper accent.
