Create a realistic image of a famous queen in her empire. The image should capture the grandeur and majesty of her reign, showcasing her in a historically accurate setting. Consider queens such as Cleopatra of Egypt, Elizabeth I of England, or Empress Wu Zetian of China. The queen should be depicted in regal attire, adorned with appropriate jewelry and symbols of power. The background should reflect the architectural and cultural elements of her empire, whether it's the opulent palaces of ancient Egypt, the grand castles of Tudor England, or the imperial courts of Tang Dynasty China. Pay close attention to historical details and the overall atmosphere to evoke the true essence of her era and sovereignty.
