I would be content in mimicking some of the "stylized-tree-tops" patterns seen in many hand-drawn fantasy maps, but I am so unskilled at drawing (and so lacking of a tablet+pen) as to be unable to reproduce anything close to.
Reliefs are more difficult with this style, the usual bevel and emboss does not work well with B/W, while lines, as suggested in the Eryemiré thread, get confused with the other elements.
