Prompt
16:9 horizontal, wide advertisement banner with a photorealistic real person as the main subject. A young Asian woman in her late 20s, slightly plump, with a cheerful and determined expression, looking confidently at the camera while holding a notebook and pen in a bright, airy coworking space. She wears a light pastel yellow blouse with rolled-up sleeves, casual beige trousers, and minimal accessories. Natural sunlight streaming through large windows, soft shadows, white and off-white walls with pastel pink and blue decorative accents. Clean, minimalist composition with generous negative space. Text burned into the top left in large bold Japanese: 「起業1年目のリアル」. Main headline in the center, very large, deep navy bold Japanese: 「最初の一歩が、未来を変える」. Layout: person on the right side, looking toward the left; text arranged on the left and center with strong contrast (white text with thick dark navy outline). The person must be rendered as a photorealistic real photograph, with natural skin texture, shot on a 35mm DSLR. Draw the specified Japanese text accurately. Do not add any other text, URL, logo, watermark, or English decorative words.

Prompt Overview
This YouTube thumbnail / SNS advertising banner targets first-year entrepreneurs and startup founders. By placing a bright, determined young woman in a bright coworking space, it appeals to real human emotions. It visually conveys the message, "Early struggles are natural, but it's still worth moving forward." The white and pastel color scheme symbolizes freshness, openness, and a clean start, while the bold navy headline emphasizes the message of change. Generous white space ensures high visibility even on mobile feeds, prompting immediate action.
The color scheme uses an off-white base with pastel accent colors to create a calm yet optimistic mood, with strong contrast from navy text to establish a clear visual hierarchy. By placing the person on the right and the text on the left, the viewer's gaze naturally moves from the headline to the face, evoking trust and curiosity. This composition is optimized for both YouTube thumbnails, where large central text stands out, and vertical-scrolling SNS feeds.
