Nice map so far. I like the symbols you are using and the swamp area is great.
You might want to put in some more mountains and crowd them together. It doesn't look like a mountain range to me, but rather a collection of lone mountains.
The same goes for the forest. It could use more symbols. If you don't want to put in anymore trees you could also drop the idividual symbols and draw areas of forest (like a texture). Not sure how that would look, but you could experiment.
To make the city and towns pop out you could try things like adding a glow effect or giving the symbols color.
Personally, I would make the roads dotted.
Have some rep for posting your first map.
