Indicación de Retrato de Mascota con Alivio de Píxeles

Convert the input photo into an upper/lower comparison: the upper half keeps the real pet/subject and its environment; the lower 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 minimalist typography around it, and a short observation line may be added; avoid making all elements the same density, and avoid watermarks or fictional text.
