Generate a half-body portrait in the style of Leonardo da Vinci's "Self-Portrait (1512)", emphasizing the fine, aged details of the subject. The image should focus on a highly detailed, sketch-like quality, with red chalk (sanguine) as the medium. Capture the subject's weathered and expressive face with deep-set wrinkles, a long, flowing beard, and a contemplative expression. Incorporate (masterpiece, ultra-high resolution, sharp focus, crystal clear details, vivid textures, high clarity, defined edges, ultra-sharp textures, subsurface scattering, while the background remains softly blurred and less defined). The overall atmosphere should evoke a sense of time-worn wisdom, with light and delicate strokes throughout, replicating the look of an old, historical sketch.
