It's a good map. But to make it more mappy...If that's a word it needs a legend stating the following.
- What colours stand for what politics. At the moment I have no idea what greenland and Iceland stand for.
- A date
- A Map projection (Mercatore by the look of it)
- Statement of maker (Made by...)
- Notations on the scaled frame telling us what is what degree 30° 60°
