Congratulations on your quick start on mapping.It took me up to post forty something to start a project.
Well I can't pretty much comment on the technical side of the map but I can comment on how it looks.IMO the map ends a bit abruptly to the west, right after the city walls.If I were you I would make the image wider so it would include something of behind the city walls to the west.At the moment it seems to me like there is half a city waiting there.But it's just my opinion.
