Here are my most current thumbnails, I have concentrated on the next part of the story, leading up to the mines, the pit, the statues and the path.
Each one has a variety of the mine, cave entrances, mountains and statues. I even added a reference to the flowers mentioned in the book, to add a drop of colour.
My next influence will be based in film and games. Lord of the Rings, Elder scrolls: Skyrim, World of Warcraft etc.
