What a beautiful image! How did you get it? I like the sepia color of the afternoon, the sun setting! I see the image and remember a poem by the Spanish writer Antonio Machado:
Walker, there is no way,
you make your way by walking.
When you walk, you make your way,
and as I look back
you see the path that never
has to be stepped on again.
The image is the metaphor of what has been lived and how the sun is already hidden from man. Excellent, @velimir.
