A Serene Mountain Lake Reflecting Autumn's Vibrant Colors

"A serene mountain lake with perfectly flat, mirror-like water reflecting the dramatic sky above. In the center of the lake, a single, solitary tree stands, its branches covered in vibrant autumn foliage in shades of red, orange, and gold. The surrounding mountains in the background are rugged and majestic, their peaks blanketed in fresh, white snow. Above, the sky is dark and brooding, filled with heavy storm clouds, creating a moody and atmospheric scene. The contrast between the warm autumn tones of the tree and the cold, imposing mountains and sky adds depth and emotion to the image. The overall composition is striking, with a balance between tranquility and impending stormy energy."
