Prompt
Create a realistic portrait of Sir William Arthur Lewis, a middle-aged man with a dignified expression, wearing formal attire, possibly a suit and tie, with a background that subtly suggests his academic and economic contributions, such as a faint image of a graph or a book; he should be depicted in a style that reflects his professional and intellectual persona, possibly with a slight hint of Caribbean influence in the background to nod to his Saint Lucian heritage.
