Prompt de Retrato de Animal de Estimação em Estilo Pixel Art

Transform the input photo into a top-bottom comparison: the top half keeps the real pet/subject and its environment; the bottom half converts the subject and one key environmental clue into a pixelated mosaic wall made of many independent square relief tiles, with real thickness, glazed reflections, rough edges, per-tile shadows, and a few missing gaps, colors extracted from the original photo, not a flat pixel filter. Keep the subject's silhouette clearly recognizable, with warm off-white walls, scattered tiles, and minimal typography around it, and you may write one short observation; avoid making all elements the same density, and avoid corner marks and fictional text.
