"Generate an image of a serene river flowing through a picturesque landscape, representing the White Elster river in Germany. The river should be depicted in a realistic style, with gentle waves and a tranquil atmosphere. In the background, include subtle hints of the surrounding landscape, such as rolling hills, trees, and perhaps a few buildings or bridges to indicate the river's path through Saxony, Thuringia, and Saxony-Anhalt. The image should convey a sense of calmness and natural beauty, highlighting the river's 257 km length and its significance as a tributary of the Saale river."
