To be honest, I don't have a huge problem with the sculpts. They may not be "exact" but I don't think they are terrible at all. I think the piece will look impressive because of the two characters being centered on the throne. (no banana peel slip on this one!
)
What I'm not excited about is the actual scene portrayed. Though I loved the scene in the film, it's not one that I would have initially selected to immortalize as a statue. Plus, the scene was powerful because of the inclusion of Gandalf (as well as Aragorn, Legolas and Gimli walking and fighting behind him.)
This is not the way I would want to have Theoden displayed. Just as I wouldn't want to see him "broken" under his horse in Pellenor fields...
I'm a fan of non-fighting statues as well so why not instead:
-Theoden on steed holding up sword
"Death! Forth Eorlingas!"
-Theoden and Gamling standing at Helm's Deep, before the battle.
And other characters:
-Sam carrying Frodo at Mt. Doom
-The four hobbits at Elessar's coronation
-The four hobbits saying goodbye at the Grey Havens
-The Fellowship cresting that hill
-Frodo, Sam and Gollum climbing the stairs at Minas Morgul.
-Bilbo or Frodo at Bag Ends at their desk writing their "books".
-Entmoot
-Treebeard carrying Pip & Merry.
-Aragorn holding mortally wounded Boromir.
