"Create a monochrome urban-style vector illustration of a pitbull’s head looking straight ahead. The pitbull, clad in a black hoodie, features prominently urban-inspired shiny gold teeth. The artwork should capture the gritty essence of city life, rendered in stark black and white to enhance the pitbull’s intense gaze and streetwise appearance. Emphasize the sharp contrast typical of urban graphic art, setting it against a dark backdrop to highlight the gold teeth and urban attire."
