a: Is the path crossing distinct or indistinct? Make sure path crossings and junctions are unambiguous.
b: Make sure neighbouring screens butt one another when they are meant to remove those white strips.
c: Ensure apexes of dashed lines have a line at the apex.
d: The left solution gives a wrong idea of how steep the slope is.
e: The tags of the fence get lost in the path. Putting tags on opposite side of line produces a far more legible solution
f: Coincident symbols must have the line feature cut or the symbols displaced.
g: Contour lines must be cut in order to show small pits and depressions. The contour line and the top edge of the cliff should be coincident.
h: Natural watercourses are situated in the bottom of valleys.
