I have to agree with what others have already said. The colors, layout and coastline of the map are very nice, but the stroke size of the coastline is a bit overwhelming. Unless for some reason you cannot alter it (e.g. either it just is your outline and you don't have another one), I would recommend reducing the size of the outline. Also, the tree icons are a bit hard to make out. You might want to find some that are more clear. Otherwise, not bad.
