原始提示词

Prompt: 【Landscape】[LANDSCAPE TYPE] 【Line Structure】[FLOWING / BRANCHING / CONCENTRIC / LAYERED] 【Palette】[COLORS] 【Scale Anchor】[TINY FIGURE / BOAT / BRIDGE / PAVILION] 【Aspect Ratio】9:16 Create a refined vertical art poster that transforms the landscape into a **line-driven topographic world**. Build the terrain with long, smooth, continuous contour lines following the natural shape, elevation, and movement of the land. Use one strong structural system — flowing, branching, concentric, layered, or diagonal — and keep every line consistent with that larger visual direction. Use 2–4 dominant colors, strong negative space, clear line-density hierarchy, and one tiny high-saturation scale anchor. Keep the landscape monumental and the human presence extremely small. Add minimal editorial typography: [TITLE] [SUBTITLE] [SHORT POETIC LINE] Elegant exhibition-poster aesthetic, strong thumbnail readability, poetic Eastern landscape feeling, highly graphic and refined. Avoid realistic photography, random waves, chaotic short lines, excessive texture, generic CGI, watermarks, logos, and copyright text.
