Styletest: 19th century historical map

[Freodin]

I am still tinkering with this. The current version is about as close to my goal as I can get it... but the methods I use get more and more complicated.
Unnecessarily complicated perhaps... I don't think most people are going to notice some of the small details.
One problem I have run into: you cannot use layergroups as layermaps / alphamaps - at least not in the current version of GIMP. So in order to keep this map non-destructive, I have to include a number of backup layers.

Now I have to come around and write all this stuff down, so that I don't forget how I did it.

What do you think? Would it be worth to invest the time, do it right and make a tutorial from it?

That is spectacular. I would love to see how it's done step by step!
