Nice map you've done there - I recognize the style, used it myself in my Mountain Realms map. A couple of comments ... the field/grass areas could use a bit more bumpiness - they are very smooth in comparrison to the rest of the map. You have to look at your rivers - rivers only go together they don't split (two rivers enter - on river leaves... like cagefigthing) so follow the flow of each river and make sure it doesn't split
The ocean is a bit strong - maybe a slight tone down .. other than that looking good, and remember to throw a scale and a compass in there somewhere
Have some rep
