Ok, I don't really know where to begin... But I'll give it a shot.
I'm a Belgian and I've only found this map by clicking captainwalrus' signature in an unrelated topic. I've been wondering for a long time if anyone would ever make a Belgium map, guess I didn't really believe enough people would be interested. So imagine my surprise when discovering that this map was made by an American!
Then I took a look at the map. And not to be rude, but... It was obiously not made by someone living in Belgium.
I'm not saying anything about graphics, because first of all this is an early stage so I understand that it doesn't look very 'Belgium-y' yet, which is normal, and second of all... I'm not good at graphics

I might give some feedback on the looks of this map later on, but not yet.
What struck me was the very weird territory planning. To me, it doesn't feel right. I read that you've picked the territories based on city names. I can see that, but I just don't think you've picked the right cities.
Just to name a few: in Oost-Vlaanderen, you've taken Gent, Zottegem en Beveren (still spelled as Breveren for now). Gent is the province's capital, so good choice. But it is located far closer to the three-way border in the middle of Oost-Vlaanderen than to the center of the region you've declared 'Gent'. Also, you cannot take Zottegem and leave out Oudenaarde. Or go for Beveren and forget Sint-Niklaas. And then we haven't even discussed whether Aalst or Dendermonde should be in the picture.
Maybe another example that's less complicated: I don't see Leuven on the map. Leuven is far more important than Tienen, Zemst, Waterloo, Jodoigne or Dilbeek. Leuven is even the capital of Vlaams-Brabant. But you didn't even take that province into account. Yes, the now pink area should be divided in two, if you wish to be realistic. That area used to be one province, Brabant (which is also not mentioned on your map), but it was split a long time ago into Vlaams-Brabant (the Dutch speaking part) and Waals-Brabant (the French speaking part). This was even reproduced in the Benelux map; take a look at it.
Really, I don't mean to offend you or look down on your efforts, because I'm glad that a Belgium map will be made, and it's brave of you to do it being an American. But before refining graphics on the gameplay you already have, I'd revise my territories thoroughly. And I suggest that you ask a Belgian's help. Because I do believe you want a realistic geographical map, one that all Belgian CC'ers would be glad to play
