Full prompt

Playful vertical graphic collage poster with a contemporary internet aesthetic, celebrating office life in the rainy season.

A black-and-white checkerboard desk in front holds desk organizers, a pen holder, and a small glass flower vase. Below, the mushroom wears bright yellow rainboots surrounded by flat blue puddle ripples. High-contrast typography layout featuring bold title blocks, flat raindrop icons, bilingual text columns, and wavy blue footer graphics. Vivid high-saturation color palette of sunny yellow, electric cyan, and clean monochrome tones, finished with a neat black outer frame border, 9:16 aspect ratio.
