An exquisite, intricate black ink drawing of a pitbull's head made entirely from a single, swirling line. As the line thickens, it spirals inward to form the dog's face, with detailed features like the nose, eyes, and ears. The line then narrows down to a single point, creating a sense of depth and dimension. The overall style of the drawing is reminiscent of classic calligraphy, with elegant, flowing lines and a touch of abstract artistry.
