I know you are very proud of making your country map, Im also very proud my Brazil map is being used already, sometimes I enter the game finder and only see how many games used it
But, you really need think about at least 5 continents. See:
Classic map: 42 countries, 6 continents - 7 countries / continent
Your map: 32 countries, 4 continents - 8 countries / continent
A map for 3-4 players dont need a gigantic continent of 12 countries, I can suggest you a dispersion of 4, 5, 7, 7, 9 countries. And, in any case, you will need some barriers, because a continent cant have more than 6 border countries.
And, delete the continent names of the map, the colours and the legend are sufficient.
