The drawing captures a sunset over the horizon, with the river stretching out calmly beneath it. The soft light from the setting sun reflects gently off the water, casting a serene glow across the surface. Along the river, rocks are scattered, their outlines defined with simple, smooth strokes. Subtle shading adds depth to the scene, giving the water a sense of movement around the rocks. The horizon in the background fades gently, blending into the calm sky. The overall effect is peaceful, as the scene transitions from day to night.
