Overall it is amazing. I would like it if there could be a bonus for holding rome or carthage and maybe have the letters S.P.Q.R in the rome territory. For the sea i like the coulor but not the texture if you could maybe have diffrent shdes in it ro somthing
I like the overall gameplay of your map with all the neutrals and all, but I'd have to see exactly what a game would look like (see the starting point) to see if it would work. I think the sea is fine the way it is, though.
