I’ve long been a great fan of Tolkein’s style, also seen on old maps. Have a look at the National Library of Scotland’s historic maps online for examples of other styles.
Googling “fractal landscape” and “procedural terrain” for ways of making nice looking landscapes with a computer. You can then turn these into shaded relief maps (some lovely OSM / Mapnick stuff linked above and via google), contours with GDAL or computer generated 3D images with fog at sunset for the cover page, perhaps using POV-Ray (although people 20 years my junior all seem to use Blender...)
Edit: Oh My. The NLS have now got a modern, seamless dragable and zoomable interface to the late 19th century 1” OS maps for the whole of Great Britain. It’s gorgeous. The “OS One-Inch, 1885-1903 Hills” is another mountain style - they draw gradient descent lines (where a marble would roll), not contours.
