Well Garmagr I'd say you are off to a wonderful start. You've done a fantastic job on those mountains and hills, and the trees look great as well (though they are a bit too sparse in my opinion, you may wish to add more of them to fill out the forests a bit more). My only real bit of constructive criticism is that the colors in this map are so muted that it's hard to make out some of the great detail that you've invested into the map. Perhaps if you added a dash more dark and light to add contrast to the map it would help these details to pop out. In addition, you may already have plans to do something with the sea, but if not, as it stands the solid blue color is a bit bland and unexciting. You might try to vary it up a bit more, e.g. by adding shallow water and/or waves. Otherwise, nice first map!
