Bradhamel art style. A detailed illustration of a grotesque, anthropomorphic rat with large yellow eyes, a long tail, and clawed feet, wearing a tattered brown hat and a torn striped shirt, crouching low while holding a brass trumpet to its ear as if listening intently, rendered in a vintage engraved illustration style with fine cross-hatching, warm earthy tones, and soft directional lighting casting a distinct shadow on a textured beige background.
