Apart from the river issues (You may have to hand yourslef in to the river police) I think your map is great. Lovely style. Clear and eye-catching without resorting to garish and over-saturated colours. Well done. I think that would be a great style to appear at the front of a fantasy novel, assuming there is a single publisher in the world who would not be so skinflint as to insist on black ink on toilet paper, which seems to be the printing norm in the industry.
