The use of
art nouveau (
http://en.wikipedia.org/wiki/Art_Nouveau ) as an indication of elvish-style naturalism is a commonplace, not only connected to Tolkien’s art.
Art nouveau owes much to Celtic designs, though NogrodtheGreat does not mention it by name.
See Anne Podles’ article on “Tolkien & the New Art” at
http://www.touchstonemag.com/archive...id=15-01-041-f . I think she is pushing her thesis over strongly.
That Tolkien much appreciated
art nouveau appears from his own art, some of which was published in the original
Hobbit. The leaf clusters on the trees in Tolkien’s illustration “Bilbo Comes to the Huts of the Raftelves” have been noted for their
art nouveau quality and the picture as a whole for its
art nouveau quality. See

NogrodtheGreat seems to be pushing what he gets from Celtic art or what Dimitri Fimi gets from it, or some of both, onto the film-makers, possibly wrongly. I am really uncertain what he would expect Rivendell or Lothlórien art and architecture to be like if not as in the films, which most satisfies most people, so far as I can see.
Simply calling the use of
art nouveau as misleading leads nowhere.
