Aside from the subdued, atmospheric lighting and the level of immersive detail, which are no small achievements, your rendition of the dwarves is particularly impressive, a blend of the traditional, gnome-like dwarves of fairy tales and the sturdy warriors heroic fantasy has accustomed us to. More Niebelungen than Trollslayers, they give a Nordic feel to the piece and thus probably make it a perfect fit for Tolkien's book.
