Pixel Art Sprite Sheet from Cat Photo

Using the provided reference images, transform the inserted realistic cat photo and visible desktop scene into pixel-art sprite charts with a transparent background suitable for PowerPoint. Extract scene elements and redraw them as simple, retro-game-style assets neatly arranged on a dark workspace grid. Includes 7 cat sprites showcasing different perspectives/poses of the reference cat: 1 frontal left-side sitting pose, 1 frontal sitting pose, 1 back-side sitting pose, 1 side-rear sitting pose, 1 side-front sitting pose, 1 side-walking pose, and 1 side-lying pose. Also include surrounding props from the reference image as separate pixel art items: 1 laptop, 2 wall chart/document panels, 1 pen holder, 1 potted plant, 3 stacks of books, and 2 desktop components of varying lengths. Maintain the cat's recognizability from the tabby white cat in the reference image and simplify all elements into clean, low-resolution pixel art for cropping and reuse in slides.
