These pictures look like an architect has had a lot of fun, and looks good for the visitors. For the primates most enclosures seem to lack cover/privacies and climbing opportunities could have been more too, based on what I can see on the pictures.
The complex as a whole definitely still has some growing in to do, but I think these exhibits are great for the primates. Almost every species was incredibly active and utilizing the climbing structures, some enclosures even having large mature trees (such as the one pictured above). The exhibits themselves definitely lack privacy, but on the day this photo was taken every species had access to their off exhibit indoor quarters. Once the vegetation builds up over the next several years I imagine it will look even more impressive, but it's already a triumphant success for both the visitors and the animals.
