I'm seeking an illustration for my upcoming horror novel, A Dream of Darkness. Set in a fictional medieval world, the story features an ominous tone, a collision of the supernatural and the everyday, and the suffocating effects of isolation upon a community. I'm in need of a detailed map to include at the beginning of the book that will showcase the fictional town/valley in which the story takes place.
I'm looking for something in the vein of the maps found in "Eragon," "An Ember in the Ashes," "The Lord of the Rings," and other novels. However, I don't want it to be too formal or "stiff" (as LOTR's seems to be), but also don't want it to be too cartoony either. Ideally, it would be crisp and detailed, but also align with the ominous/horror tone of the novel. Black and white.
