Retrato al Carbón de Guitarrista Acústico

A vertical charcoal and graphite portrait of a [handsome young man] with [wavy, tousled hair], sitting on a [wooden stool] and playing an acoustic guitar. He has a warm, gentle smile, looking down at the strings with a focused yet relaxed expression. Traditional fine art style with visible charcoal strokes, soft blending, and high-contrast shading. The background features a cozy, dimly lit room with softly blurred bookshelves and a window, creating an atmospheric charcoal bokeh effect. Rich textures on his knit sweater and the polished wood of the guitar, rendered on textured cream-colored paper.
