As a serious map developer on a variety of projects I can tell you that making such maps is not easy. Especially if like these you try to represent everything. Europe looks really screwed up because Europe is very small. It just doesn't deserve many tiles. You need to decide between preserving shape, area, gameplay, relational positioning etc.
Personally I feel you are way better off just cutting out the arctic areas (like they did in the south but not the north).
