I like the general look of your map, but there are few things that might want to consider.

-The mountains do fit in quite well, but it somehow bothers a bit that they are drawn with much finer lines than the rest of the map. (try reducing the width of other lines and make them also a bit finer.. or make the mountains rough & thick also)


-The forests are represented by quite sparsely placed trees that follow quite the same density trough the whole map --> the actual forest area limits aren't that clear

What you might want to try is to place the trees closely enough to form a forest like in this post: http://www.cartographersguild.com/showthread.php?t=4718

Just some thoughts...
