Any such suggestions would depend on how you define decent. They would also depend on what purpose this map is serving. As Waldronate is fond of saying (am paraphrasing here because he says it so much better than I can/do), as long as the is conveying all the information it needs to convey, then it is a decent/good map. While maps can certainly be pretty, if they don't give the players/readers the information they need to know, they aren't doing their job.

Personally, I think it looks fine. Places are labeled, the prominent terrain features are identifiable, and you have a scale for determining travel time.
