That looks a lot better with the bevel on the land too. How about using an Edge Fade, Inner on that sea contour to blend the two ocean colours together just a little?

The fills look better now they give a hint of what they are supposed to be :)

What are trilathons?

I like the idea of a beacon.

A camp would be nice, but maybe a little too much work for the time, bearing in mind I have yet to do the standing stones and the waterfalls, but we'll see.

Part 1 will be published soon with all the trees and forest stuff, including the ruin parts.

I'm now working on part 2. So far I've done cliffs and heather. Standing stones are next, and then waterfalls and bridge sections. Bit of a strange bald spot in this map. I haven't decided what to put there just yet.

You could use a variety of styles that might reflect the culture of the map maker. These days most real world maps seem to look fairly similar, but that was not always the case.
