Annoyed Chibi Character Sticker Sheet Prompt

Create a clean white-background anime sticker-sheet illustration showing exactly 16 chibi-style annoyed people popping up from rectangular patterned mats, arranged in a precise 4 columns by 4 rows grid. Each character is cropped at the torso behind the mat edge, with oversized heads, rosy cheeks, heavy-lidded angry eyes, small frowning mouths, expressive messy hair, thick black line art, soft cel shading, and a cute but confrontational mood. Several characters thrust an oversized index finger toward the viewer in strong foreshortened perspective as if scolding or saying “you”; others glare with folded arms or a slumped irritated posture. Use no text, no speech bubbles, no watermark, and keep generous white spacing between all stickers. The 16 discrete characters are: 1) black short wavy hair, navy hoodie, pointing, black-and-white houndstooth mat; 2) brown twin ponytails, yellow sweater, pointing, blue-and-white striped mat; 3) dark brown high ponytail, olive hoodie, pointing, pink polka-dot mat; 4) ash-blond short hair, gray cat-print shirt, pointing, teal dotted mat; 5) curly dark-brown bob with hair clips, tan jacket, pointing, gray houndstooth mat; 6) black hair in two braids, lavender sweatshirt, arms folded, blue double-border mat; 7) messy light-brown bun, cream sweater, arms crossed on peach polka-dot mat; 8) brown bob with star hair clips, cream cardigan over striped shirt, pointing, yellow dotted mat; 9) black bob, dark green hoodie, arms crossed, black-and-white houndstooth mat; 10) brown ponytail, pink sweatshirt, pointing, purple bordered mat; 11) light-brown wavy bob with round glasses, beige hoodie, worried-annoyed expression, mint polka-dot mat; 12) brown twin pigtails, dark green cardigan, flat unimpressed stare, orange dotted mat; 13) tousled brown hair, gray hoodie, pointing, pale blue houndstooth mat; 14) dark brown ponytail, olive hoodie, pointing, red mat with thin white border; 15) messy brown bun, pale yellow cardigan, pointing, pink dotted mat; 16) short black hair, charcoal sweatshirt, blushing scowl, navy dotted mat.
