Affiche pop rétro de personnage en style anime aplat

Using this character, create a retro × pop key visual. Use the reference image only as a character reference; do not reuse the composition, pose, background, or framing of the original image. Flat-leaning anime coloring. Slightly thick outlines. Don't pack in too much information; compose the frame with whitespace in mind. [insert composition, situation, etc. here] Express the retro feel naturally through color palette, atmosphere, composition, and design sense — not through old symbols or text effects. Avoid excessive detailing, hyper-dense AI illustration, particle effects, information-overloaded backgrounds, and harsh glaring lighting. Make the image tidy like a poster — quiet and stylish.
