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.
Amazing! Your illustration are exactly what I saw in my mind when I read "The Hobbit" for the first time. I still can't equalize Jackson's film with a book, their personages are completely separate in my mind.
Love the gloaming atmosphere you've achieved. It's great. also we are trying to braid my boyfriend's bushy beard like that but sadly real beards tend to be slightly on the not-so-lush side. Sad, because it looks friggin awesome!
