You should add a land tile in the weird bay east of mount Vesuvius, also I think france and italy should get one more territory each to balance the density around them (splitting northern france and southern italy, slightly adjusting the other territory for consistency).
EDIT: I would like a better represented tuscany, but I see there's not enough space...
On another note, would it be possible to create a bigger map? I read you can't have more than 199 hexes in longitude, but can such a map theoretically work?
Also, could you have a map with more hexes in latitude?
(Just to be clear, I'm not asking you to create such a map, I'm just asking if you have this info)
