I think this would have more impact if the wall was sharper. Nice sky, though perhaps a little overdone.

Looks like you need to clean that sensor! I think a closer crop or composition would have worked better. There's a lot of potential at this site.

I like the image and the composition overall, but nothing really stands out to me about this. If the sky was clear, it would be better, with three simple fields. But as-is, this has too much intricate detail throughout the shot to be zen-like in the way I am familiar with the concept.

Great composition but I believe the clouds give too much to this to make it zen. A clear blue sky would make this really shine in the theme.

All those rocks working together
to be a wall.
Fine line for the horizon.
