Really glad the right decision will eventually get made 
why does it need to be unique? it is a gorgeous point of interest that i would definitely seek out in exploration.
Hm i am not sure perhaps because its everywhere here in the entire area. It just felt like decoration. Personally i wont “explore” this
Sabes cuál es el problema? Que quienes revisan y la gente de aquí en general son de países de primer mundo, una pared así está en todos lados donde viven, por ende no les parece algo relevante, los estándares de criterio siempre han sido así cuando deberían ser acorde al país, no es lo mismo algo relevante en el centro de una ciudad de primer mundo que en nuestro cerro 
Yo e enviado y me han aprovado paredes de esas aqui en Los Angeles.
I am not the one rejecting the nomination. It was rejected because reviewer feel the submission lack uniqueness or historical and cultural meaning. Anyway all good if its approved. I am not against the nomination at all
Most of the people reviewing your nominations will be from your country
Incredibly rare here. And permanent decoration can be considered something beautiful which is a good place to explore. So I think you’re actually saying its eligible but that you hadn’t realised it?
Painted electrical boxes are quite common in some areas and those are considered a decoration that makes them explore-worthy. And the green wall is many times the scale and complexity of that
