17th-18th century Caribbean

To be honest, I really don't like those outlines around the landmasses. They're way too obstructive, especially in a map like this. The archipelagos, like the Bahama Islands and Lesser Antilles, are so confusing I almost can't read them. They lines also randomly jagged or smooth, which looks odd. And because they are made by an automated process (I assume, so correct me if I'm wrong), there's also a few "pixel artifacts" here and there.
If you insist on keeping them, I suggest at least placing them closer to the coastlines, without that much space between them. That way they don't stretch out too far and start overlapping with lines from other islands, which just makes a mess of thick and thin lines.
But hey, that's just my opinion, and you definitely shouldn't listen to that.

How you actually turn this into an antique style map, I think you can find a great tutorial for, somewhere on this forum.

Oh, and welcome!
