                                            Generate an image of a 18th-century American plantation owner, specifically Robert Carter III, standing in front of a grand estate, surrounded by lush greenery and possibly a few enslaved people in the background, with a serious and contemplative expression, reflecting his role as a politician and plant species expert, with a subtle hint of the emancipation document he is notable for; in a realistic and classical style reminiscent of portraits from that era.
