Retrato en pixel art de hombre en sillón

A sharp-edged, high-detail [pixel art illustration] based on the reference photo. A stylish young man with [dark, messy hair] sits casually leaning back in a [modern tan armchair], wearing dark sunglasses, a grey graphic t-shirt, and wide-leg blue jeans, lifting one hand to adjust his sunglasses. The background shows a white brick wall decorated with three framed sketches. Maintain crisp outlines, clean cel-shaded aesthetics, and the original color palette throughout.
