将猫咪照片转换为像素风精灵图表

Using the provided reference image, turn the inserted realistic cat photo and the visible desk scene into a transparent-background pixel-art sprite sheet for PowerPoint. Extract the scene elements and redraw them as clean retro game-style assets arranged on a dark workspace in a tidy grid. Include exactly 7 cat sprites showing different views/poses from the reference cat: 1 sitting front-left, 1 sitting front, 1 sitting back view, 1 sitting side/back view, 1 sitting three-quarter view, 1 walking side view, and 1 lying down side view. Also include the surrounding props from the reference as separate pixel-art items: 1 laptop, 2 wall chart/document panels, 1 pen holder, 1 potted plant, 3 book stacks, and 2 desk pieces in different lengths. Keep the cat recognizable as the same tabby-and-white cat from the reference, but simplify everything into crisp low-resolution pixel art suitable for cutting out and reusing on slides.
