You could replace the <> with a simple " ----- " in the legend.
Or you on the map gameboard you could add an arrow pointing > from Para. right near the icon, and on the other side near Drum you could point an arrow pointing the other way on the line < ...if the makes any sense. You could do that to all the routes. Maybe that would solve things?
Also, you are probably finished working on the Opera House image in the bottom left, but if you so happen to feel inclined, the water looks a little flat, when compared to the brush strokes used for the Opera House. Maybe you could use a similar stroke to make a little wave or two?
