You're probably planning to fix it already, but that farmland cutoff at the top looks a bit artificial being so straight and all. A few trees covering up parts of the edge helps a lot here.

Yea, you can put a lot of things on small islands. I've been to a couple of the Caribbean ones. Barbados for example is 169 square miles, which looks about similar to yours in size, and has a population of 300 000 and lots of interesting locations.

There is a list of fonts on the FAQ page for the atlas, but it is quite a bit outdated by now. I don't know of any other lists.

As for license questions, those are best sent straight to ProFantasy

Thanks @Wyvern, the maps are now available in the atlas.
