Prompt
"Generate an image of a serene, winding river that stretches into the horizon, symbolizing eternity and continuity, in a style that reflects a blend of realism and abstract elements. The riverbanks should be adorned with lush greenery and perhaps a few distant, misty silhouettes of trees or hills, evoking a sense of depth and mystery. The sky above should be a soft, pastel hue, suggesting dawn or dusk, with gentle, wispy clouds. In the foreground, subtle hints of musical elements, such as a barely visible guitar or a few floating musical notes, should be incorporated to subtly nod to the album's musical nature, without overpowering the landscape. The overall mood should be tranquil, reflective, and slightly ethereal, capturing the essence of Pink Floyd's 'The Endless River' album."
