Might have to agree with above; the research one seems best detailed relative to size.
I will say, it's not often you see people building in cloth and making it look good anymore. That's one of the things I miss from classic; people were actually good at using cloth, like you've done pretty well.
This is awesome, I do agree that there does need to be a city or at least a big port for the container ships. But its really cool.
Do not fear I'm in the process of expanding the ports and adding cranes and warehouses and eventually city buildings, however the places like the jungle logging port I'm going to keep fairly bare as I like the idea of sailing for miles to a jungle, loading some freshly cut logs and just leaving it how it was.... a jungle
