Style direction:
A friendly hand-drawn public-service poster style built from chunky irregular marker outlines,
oversized blue-bordered speech-panel typography, simplified cartoon people, flattened civic
props, pastel paper backgrounds, warning-sign motifs, and intentionally naive perspective.
Keep visible:
- Preserve the core visual identity: A friendly hand-drawn public-service poster style built from chunky irregular marker outlines, oversized blue-bordered speech-panel typography, simplified cartoon people, flattened civic props, pastel paper backgrounds, warning-sign motifs, and intentionally naive perspective.
- Illustration: make 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.
- Layout: reserve the upper half or upper band for a huge rounded speech-panel sign with a thick marker-blue border and off-white interior.
- Characters and setting: place one or more simplified cartoon people in the lower half with playful scale distortion, oversized hands, signs, or props, and intentionally naive proportions.
Avoid:
watermark, username, creator ID, platform logo, QR code, app UI, signature, copied reference
text, copied reference characters, red telephone, legal theme, date range, no-access sign, exact
layout, brand logo, licensed character, recognizable person, 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,
dark cinematic mood
Do not copy source content, real logos, watermarks, platform UI, QR codes, or exact
reference layouts. Keep the visual system, but change the subject, text, and scene.
