Boceto Vintage de Hombre y Caballo

Use the given photo and create a highly detailed pencil and ink sketch of a handsome man with curly hair and a beard, wearing a tailored wool coat and Chelsea boots, sitting on the ground in front of a rustic horse stable. Behind him stands a majestic horse. The artwork features intricate cross-hatching, fine line work, and technical drafting elements like scale rulers, measurement lines, and architectural annotations. The drawing is on crumpled, slightly stained parchment paper with a visible coffee ring in the corner, giving it the look of a vintage field study or an architect's lost sketch.
