Sorry it's been so long!

I spent a long time getting the mountains and hills just right

...and then started on the Structures. These are the default cities.

And here are some towns and hut villages.

It sounds like what you really need for those wings is a symbol rather than a texture. Feathers have a definite direction, so a fill would look wrong in all but one direction because you can't align a Texture Overblend effect.

As for scales...

I might have stopped work to spend a few hours churning out a few scale type fills that might or might not have been what you are looking for, but I'm on a time limit with CC4 Overland and a bit too busy to stop right now. Unless this is for a commercial map I would suggest searching for "Seamless scale texture" and seeing what comes up.

I may be misunderstanding the secondary problem you mention there about lack of detail, but when you create a hi res world in FT it's usually too much detail that's the problem.

Perhaps increase the Editing Size of your world in World Settings->Editing? That may change the coastline a bit, but you will get more detail.

Remember to hit Appy.

It has a lot of power. Familiarity with a style makes everything much easier.
