Contour Landscape Poster Prompt

Create a vertical 9:16 English landscape poster built primarily from flowing contour linework and bold colour. Design the landscape first with strong, simple, readable landforms — monumental mountains, cliffs, valleys, rivers, ridges and forests — so the composition stays powerful even at thumbnail size. Let long continuous lines follow slopes, ridges and geological folds, with calmer horizontal lines in the sky. Use ink-black and dark-blue landforms with glacier blue, muted teal and warm ivory linework, plus small burnt-orange accents on selected ridges. Add refined editorial typography with an elegant high-contrast serif title, and keep the result feeling like a complete collectible artwork.
