I would like an AI-generated image of a young fat male human alchemist character set in the Discworld universe, styled like the artwork of Josh Kirby. The alchemist should have a whimsical, detailed, and slightly exaggerated appearance, characteristic of Kirby's illustrations. The scene should be vibrant and fantastical, with elements such as bubbling potions, ancient books, strange contraptions, and magical artifacts. The alchemist should look eccentric and intriguing, wearing traditional alchemist robes but should not resemble a wizard. Ensure the alchemist is young and clean-shaven, without a beard. The background should be simpler with fewer bottles and shelves, capturing the essence of a mystical laboratory without being overly cluttered. The dominant color in the image should be blue. The style should capture the unique, colorful, and dynamic essence of Josh Kirby's art.
