アクセントカラー1色の旅行ノート・イラスト

Create a charming editorial travel illustration of {DESTINATION} in a simple hand-drawn doodled style, as if sketched by hand with a black felt-tip marker in a travel notebook. The illustration should feel personal, spontaneous, and imperfect rather than digitally designed, like a drawing someone might casually create while sitting at a cafe after exploring the destination.

Color palette: keep the illustration almost entirely black and white. Use only one accent color: {ONE POINT COLOR}.

Draw entirely with black felt-tip pen lines. Use slightly wobbly hand-drawn contours, natural line variation, loose marker strokes, sketch-like confidence, subtle imperfections, slightly open line endings, uneven hand pressure, and occasional overlapping strokes. Every line should clearly look handmade.

Illustrate the unique atmosphere and instantly recognizable identity of {DESTINATION} rather than producing a realistic cityscape. Select the destination's most iconic landmarks, characteristic architecture, local transportation, famous scenery, native plants, local animals, regional food, and cultural objects. Focus on the spirit of the destination instead of literal accuracy.

Arrange the selected elements into a balanced editorial composition with generous white space. The layout should feel open, light, and effortless, similar to a designer's travel sketchbook. Allow objects to overlap naturally without becoming crowded. Apply the accent color sparingly to selected details such as water, sky, windows, signs, clothing accents, decorative highlights, or small architectural features.

Mood: warm, friendly, relaxed, playful, minimal, editorial, and contemporary. No photorealism, no 3D rendering, no painterly effects, no gradients, no heavy shadows, no glossy lighting, no vector-clean artwork, no excessive detail, and no busy composition.
