Campin_Killer, here is something for you. Please take this all in the spirit of that as a new map maker, I want to help you get this made and I understand that some of this may be beyond you at the moment, but all you need to do is ask away.
Firstly, you need to decide on what you want your map to look like as right now it is just a mixture of shape and colour. Here are a few ideas for you to consider.
As this in historical map, I would suggest one of the old paper ones. The first one would look really nice for this. When you decide on what you want the map to look like, we can go from there and start to get things moving along. I am not asking you to make it your next draft, but this sort of focus will be needed.
