Anime cel illustration, clean confident linework with tapered weight, flat colour fills with hard-edged cel shadows in a single shadow tone, bright high-chroma accents against a restrained base palette, crisp specular highlight shapes on hair and eyes, even ambient light — no photographic exposure, no gradient haze. Clean dark-toned outline, heavier on the rounded jaw and outer silhouette, lighter interior detail. A single cute character emoji face fills the square frame, centered for immediate readability, with a rounded face shape and an exaggerated angry side-eye expression: narrow sharp eyes, single small highlights, strongly angled brows, gaze directed sideways, tense tiny mouth, cheeks slightly puffed. Simplified nose and mouth, clean jaw line, flat blush accents. Simple clumped hair silhouette framing the face, with a hard highlight band. Cute 5-head chibi proportion implied by the compact emoji crop. Flat even daylight, minimal hard cel shadow. Bright warm accent colors on the eyes and cheeks, clean pale background color field. No text. No photo, no photorealistic rendering, no camera bokeh, no film grain, no realistic skin texture, no 3D render, no sketchy unfinished lines.
