Create a highly detailed, realistic illustration of an anthropomorphic bunny character, inspired by the works of Margaret Brundage. The bunny should be holding a basket of flowers, wearing patent leather, and giving a thumbs up. Incorporate elements of benevolence and whimsy, with a touch of the gaudy and ornate. The character should be depicted in a large, tall format, with a white ascot and a potion belt. Ensure the image is in high definition (4K or 8K) and features micro details, lifelike details, and adherence to the golden ratio. The style should be reminiscent of Mr. Clean and Constantine, with a dash of elegance and sophistication. The output should be a high-quality image, trending on Pinterest, with a top lid and a teapot in the background.
