Create a realistic illustration sized precisely at 7 cm by 2.50 cm, focusing exclusively on the landscape from the legend of Kaldi, the Ethiopian goatherd who discovered coffee. The scene captures the rugged hillsides of Kaffa, Absinia, with wild coffee shrubs prominently featured, their branches laden with bright red berries. The narrow, elongated format emphasizes the lush greenery and the rolling hills that stretch into the distance. The twilight sky adds a mystical atmosphere, with soft hues blending into the horizon. The overall style is hyper-realistic, with detailed textures in the foliage, the coffee berries, and the natural elements of the Ethiopian landscape. This illustration should evoke the serene and enchanting nature of the region where the legendary discovery of coffee took place, fitting perfectly within the compact dimensions.
