Prompt
Create a realistic portrait of Immanuel Kant, a middle-aged man with a stern expression, wearing 18th-century Prussian attire, sitting in a study with books and papers surrounding him, with a backdrop of Königsberg's cityscape; incorporate elements that reflect his philosophical works, such as a copy of "Critique of Pure Reason" or a diagram of the categorical imperative, in a neoclassical style that echoes the Enlightenment era.
