Art style: Realistic cinematic nature documentary.
A wide-angle view of a glacial stream winding through a valley of grey stones and sparse green vegetation. To the left, a steep hillside covered in emerald grass rises sharply. In the far distance, jagged mountain peaks with patches of snow stand against a sky filled with soft, white clouds. The lighting is natural and diffuse, emphasizing the vastness of the landscape and the cool, crisp atmosphere of the high-altitude valley.
