​A vertical charcoal and graphite portrait of a {argument name="subject" default="handsome young man"} with {argument name="hair style" default="wavy, tousled hair"}, sitting on a {argument name="object" default="wooden stool"} and playing an acoustic guitar. He has a warm, gentle smile and is looking down at the strings with a focused yet relaxed expression. The style is traditional fine art with visible charcoal strokes, soft blending, and high-contrast shading. The background is a cozy, dimly lit room with blurred bookshelves and a window, creating a soft, atmospheric 'bokeh' effect in charcoal. Rich textures on his sweater and the polished wood of the guitar, rendered on textured cream-colored paper.
