BACKGROUND RULE: Use a clean white or near-white background. Keep the upper-left typography area mostly pure white and spacious. Do not use peach, beige, cream, warm tinted background wash, or paper-like background color. Warm tones may appear only in architecture, flowers, clothing, café details, and small objects.

Add local architecture, a small café or street-side shop, a local transport sign, a slim street lamp, trees, flower pots, and a few refined city-specific details. Optional secondary landmark may appear very small and subtle in the far background, but it must not compete with the primary landmark. Avoid landmark collage or overly dense city elements.

Show small natural daily-life moments: two people talking at a café table, one person walking quietly, one person taking a photo, and optionally one person sketching or jogging. Avoid crowds. Avoid a single hero character. COMPOSITION: Keep large clean white negative space in the upper-left. Place the main landmark clearly in the middle-to-background.
