<https://s.mj.run/StrFLKV2Uzs> Create a monochrome illustration in shades of grey depicting an African scene. The scene should feature tall palm trees with long, slender trunks and lush fronds dominating the landscape. In the background, include traditional African buildings with flat roofs, dispersed among the palm trees to add depth. Include several groups of people in the scene: a group standing and talking in the center, and two people sitting or kneeling near a bush on the right. The vegetation should be dense with bushes and shrubs, adding texture throughout the image. The sky should be partially cloudy, with clouds in various shades of grey to enhance the depth and dimension of the scene. Ensure the entire image maintains a consistent monochrome palette in shades of grey.  --s 250 --ar 2:1
