Prompt

Create a naive-marker-psa-poster-style image, aspect ratio 9:16. A simplified cartoon subject (group, students, volunteers, workers, neighbors, mascot, or public-service character) performing a public-service action (raising a hand, pointing at a sign, sorting objects, passing supplies, checking a list, or holding an oversized prop), featuring an oversized object (book, tool, sign, device, food item, toy, bin, clipboard, safety item, or public prop), in a simple public setting (school area, street corner, library, garden, transit stop, clinic, market, lab booth, recycling station, or community space). Include flat tiny buildings, signs, arrows, grass tufts, cones, paper labels, small rocks, alert marks, bottle icons, paper scraps, and doodle symbols. Characters wear simple school, community, worker, volunteer, lab, neighbor, or everyday cartoon outfits with flat marker-color blocks. This is a finished raster poster, not a photo, SVG, UI mockup, or clean vector icon set. Use thick uneven black marker outlines, flat hand-colored fills, rounded stroke ends, subtle paper grain, marker scuffs, imperfect edges, and low-polish scanned-poster softness. Reserve the upper half or upper band for a huge rounded speech-panel sign with a thick marker-blue border and off-white interior. Place a short bold public-service headline (maximum three to five words) inside the sign as massive rough black block letters. Add a small label in a rounded red or blue capsule near the headline. Place one or more simplified cartoon people in the lower half with playful scale distortion, oversized hands, signs, or props, and intentionally naive proportions. Build the environment from flat doodled public-scene icons: tiny buildings, signs, cones, grass tufts, arrows, rocks, labels, alert marks, and simple yellow ground patches. Use a pale blue background, cream panel, marker blue frame, coral red accents, warm yellow ground, soft skin pink, grass green, chalk gray, and deep black ink. Keep the poster friendly, instructional, childlike, approachable, and lightly comedic. Include a lightning bolt, exclamation mark, hand sign, arrow, triangle warning icon, circular arrow, sprout burst, or comic burst as a simple graphic accent. Avoid watermarks, usernames, creator IDs, platform logos, QR codes, app UI, signatures, copied reference text, copied reference characters, red telephone, legal theme, date range, no-access sign, exact layout, brand logos, licensed characters, recognizable people, photorealism, 3D render, glossy vector art, clean corporate icon set, gradient lighting, airbrush shading, thin elegant line art, realistic anatomy, correct architectural perspective, long paragraphs, dense fine print, and dark cinematic mood.
