It reminds me of "Runaway Train".
I built the exact same backyard fence at my place,...without the train! Only difference is I topped off the posts with decorative screw in wooden ball mounts that extend up 5 inches higher than the rest of the fence just to give it a little POP and a more finished look. Now Im working on my wife to let me do a permanent outdoor bar,....she's not a fan,...but I'll win in the end. LOL Mine are also topped off with solar lighting as well.
