A Big Sound Unboxed

Square bold poster illustration, expressive hand-drawn marker art. Oblique overhead view of one opened, comically squat red shipping carton positioned toward the upper left. Oversized yellow over-ear headphones sit snugly in a simple cobalt-blue insert: enormous rounded earcups connected by a thick arching headband, immediately recognizable. Four broad carton flaps spread asymmetrically, establishing a lively diagonal silhouette. Keep the headphones the clear focal point. Flat primary-colour blocks, broad imperfect marker fills, dark pressure-varied pencil contours with occasional loose overshoots. Warm ivory background, a single simple blue offset shadow beneath the carton, shallow depth and consistent edge clarity. Leave generous uninterrupted ivory space at lower right for interface placement; do not draw a button. Finished editorial composition, deliberately simple and legible at thumbnail size. No people, intricate hatching, text, labels, logos or watermarks.
