Prompt
Create a realistic portrait of Zachary Macaulay, a British abolitionist from the late 18th and early 19th centuries, depicted in a formal, neoclassical style. He should be shown wearing attire typical of the era, such as a tailcoat and waistcoat, with a serious and determined expression, reflecting his commitment to the anti-slavery movement. The background should subtly hint at his involvement in the movement, possibly with a faint image of a map of Sierra Leone or a related abolitionist symbol, without overpowering the focus on Macaulay himself. The color palette should be dignified and somber, fitting for a historical figure of his stature and the gravity of his work.
