પારદર્શક પૃષ્ઠભૂમિવાળો સ્ટીકર અવતાર બનાવો

Based on the appearance in the reference photo, create exactly 1 avatar stickers in expressive cartoon illustration style.
Keep the same recognizable person, facial features, hair and accessories across all stickers. Do not change their apparent age.
Use one single avatar on ONE square image. Row-major emotions: joy. Make the emotions expressive.
Each sticker must be fully inside its own equal cell with generous empty margins. No overlaps or cropped heads.
Return real alpha transparency outside the stickers and in all gaps. No fake checkerboard, solid background, frames, text or watermark.
Give every sticker a crisp contour and a thin white cutout outline so it can be placed in a messenger.
Additional appearance/style notes (the output layout and transparency requirements above remain fixed): Preserve her dark wavy shoulder-length hair and white shirt.
