Park 20-Minute Effect Healing Poster

Full prompt

A soothing wellness poster set against a light sage-green background decorated with a clean pattern of small green dots. In the center is an irregular polygonal picture frame with a thick green outline showcasing a real outdoor photograph of a lush green lawn and softly blurred park trees. In the foreground, two small dogs stand side-by-side on the grass looking directly into the camera under bright, even daylight. Bold white title text with a green stroke across the top reads 'The 20-Minute Park Effect', above a curved white banner containing the green subtitle 'Step Away from the City Rush, Breathe Fresh Park Oxygen'. The composition is embellished with playful white and green hand-drawn lines and solid green smiley-face icons at the top right and bottom left, creating a fresh, restorative aesthetic without commercial branding, 3:4 aspect ratio.
