Those are some of the nicest I've seen. Love the ones with the large massings of ferns. They use repetition really well in all those examples too.I think the benefits usually given for interior green wall projects are extremely overstated. They look nice but I have a feeling that for the cost of the electricity to light the wall and recirculate the water you could install a much more effective air filter. Install them because they're cool, not because they're going to be effective at cleaning your air.Exterior projects are entirely different and I really think they're a great idea.
Not a huge fan of the latest fad of succulent green walls. But the ones you posted are mostly ferns and bromeliads and philodendrons that are actually meant to be growing that way. Works a lot better imo.
