GPT Image 2.0 プロンプト - [Country] 連続線のレトロインク旅ポスター

Create a premium vertical 4:5 travel poster for [Country], illustrated as one elegant continuous hand-drawn line-art composition. Instead of placing landmarks separately, make them flow organically into one another, as if the entire country was drawn in a single uninterrupted travel sketch. Combine the country’s most recognizable architecture, landscapes, culture, food, transportation, nature, and tiny everyday details into one beautifully balanced scene. Use bold black ink outlines, delicate cross-hatching, playful imperfect hand-drawn details, subtle vintage-poster typography, and a mostly warm off-white paper background. Add only 2–3 signature accent colors inspired by the country. Include: One dominant iconic landmark A second architectural landmark subtly integrated into the skyline A famous natural landscape in the background Local transportation Traditional clothing or cultural detail A recognizable food or drink Small street-life moments Birds, clouds, plants and tiny decorative elements Handwritten labels pointing to selected elements At the top, use a large playful hand-lettered title: “[Country]” Below it, add a tiny elegant subtitle: “A little world to discover” Make the composition feel collected, whimsical, editorial, nostalgic and handcrafted, like a beautifully illustrated travel journal rather than a generic tourist poster. Avoid photorealism, gradients, 3D rendering and excessive colors. Clean white space around the illustration, highly detailed ink work, charming imperfections, premium stationery aesthetic, screen-print texture, sophisticated yet playful.
