Use case: identity-preserve. Input image: the supplied original transparent akiko portrait is the exact character identity, body and style reference. Create ONE transparent horizontal sprite sheet with EXACTLY THREE equally wide columns, three fully separate copies of that SAME adult character. Canvas approximately2400x1000,2.4:1 panoramic; each equal cell is4:5. Copy the exact same waist-up body, clothes, pose, hand positions, prop, skin tones, haircut, camera angle and scale into each cell; ONLY change the facial expression. Identity details: Black Japanese teacher Akiko: rich brown skin, short coily bob, gold heart hairclip, mustard cardigan, opaque ivory blouse, blue notebook held in both hands. Left-to-right facial expressions:1) warm happy smile;2) thoughtful and reflective, soft closed mouth and attentive eyes;3) gently concerned, subtly raised inner brows, small worried mouth, still warm and composed. No pose changes, no gesture changes, no hand-to-face gestures, no prop movement, no changed hairstyle. Preserve the reference's crisp early-1990s pixel-art outlines, warm palette and ordered dithering. Align all3 heads, shoulders and waistlines identically; center them at one-sixth, one-half and five-sixths of the sheet width. Comfortable transparent margins around each full head and silhouette; minimum8percent empty transparent space within each cell on its left and right. No touching or overlapping copies, no cut-off hair or hands, no mismatched scale. All white/light clothing and props stay opaque; background is genuine transparent alpha, including the gaps between columns. No solid backdrop, checkerboard drawing, scene, shadow, labels, numbers, text, borders or watermark.
