This is very true, Joe. If all circles were as perfect as the day they were created I could just put fractalised polys of stone there and give them strange looking shadows, but there are also fallen and leaning stones that can give a much better feel for the nature of all the stones. Well, that's what I hope anyway.

I think the black looks better :)

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.
