Torn Paper Ink Landscape Poster

Create a vertical minimalist paper-art landscape poster. Use a pale warm-gray paper background with a winding S-shaped torn opening that reveals a colorful ink-inspired landscape inside. Within the tear, compose a river flowing from top to bottom, layered green hills, terraced fields, small waterside buildings, delicate trees, and one quiet boat as the visual anchor. Make the torn paper edge feel dimensional, with subtle shadows, relief depth, and clean negative space around the central landscape. Use soft greens, muted reds, clear blues, and restrained ink-wash texture. Keep the final poster text-free or reserve one blank editable title area; do not add fixed calligraphy, dates, country labels, signatures, seals, watermarks, logos, or unreadable typography. Deliver a refined vertical poster suitable for gallery prints, cultural campaign visuals, interior decor mockups, or editorial covers.
