Prompt
"Create a realistic portrait of Rosa Luxemburg, a Polish-German revolutionary and Marxist theorist, in a contemplative pose, surrounded by books and papers, reflecting her work as an economist, philosopher, and writer. Incorporate subtle hints of her activism, such as a pen or a pamphlet in her hand. Use a muted color palette with a focus on earth tones to evoke a sense of intensity and intellectualism. Style: Realistic, with a touch of early 20th-century European art."
