Prompt

Create one polished, source-grounded creative image. Design a believable widescreen advertisement mounted inside a modern commuter train for an invented business book titled DESIGNING SMALL WORLDS by MIRA SEN. Show a clean original cover mockup beside concise copy: NOTICE MORE. BUILD LESS. TEST EARLY. Add a small button-like phrase READ THE FIRST CHAPTER. Use navy, cream, and signal orange, strong typographic grid, real train reflections and perspective, commuters softly out of focus. No bestseller badge, review quote, sales claim, publisher logo, QR code, or real brand. Use only original worlds, characters, products, and organizations. Every depicted person is clearly an adult aged 25 or older. Do not imitate a named living artist or reference an existing franchise, celebrity, public figure, brand, trademark, or logo. No sexualized framing, gore, deceptive official seals, unsupported real-world claims, watermark, or signature. Keep anatomy, object construction, repeated details, lighting, perspective, and requested layout coherent. Render only explicitly requested text and no accidental extra lettering.
