Good first map.

The size of the city labels is very disproportionate to the rest of the labels (at this resolution they are actually unreadable) so you might want to go back and enlarge them.

Also, youve got some kooky rivers going on there - though it isnt your world so that aint your problem for some reason non-cartographer DMs dont tend to have a very good understanding for the way rivers form, generally speaking.
