Tolkien's Art for The Hobbit - Group 1

I forgot to post our cover sketch over fall break.  My group was assigned to analyze Tolkien's pieces depicting Mirkwood and the trolls.  We chose to focus on the trolls. His work here was fairly limited, but we felt he displayed many elements and principles of art in these pieces.  We found three primary elements, line (mainly implied line), shape, and form.  For principles we observed contrast, movement, emphasis, and pattern.  We took each of these into consideration when sketching a draft of our cover.  We also chose to include smaller images of things in the novel in the picture's border, as well as Dwarvish runes, as a nod to the style Tolkien uses in many of his other pieces.
