I love it laMoria, thank you for putting your time and effort into this.
However before we implement this onto the server, I have a few details which I think should be changed first:
1. Could you make no ridge there so a waterfall can be physical and we don't have to dig it all out.
2. I don't remember an island there because that is where the artist tower will be.
3. Could you add the tiny islands which were there and maybe also a rocky beach like the ones you sometimes find on mountain lakes, little pebbles.
4. I think this looks a bit small but it is hard to tell.
5. I don't know, but it looks like something is missing, maybe add a slight ridge to connect the lone mountain to the rest.
6. Could you add a sandy beach here, I have a new idea
7. I don't see a dig out of a river, don't know if this is possible.
Thanks for all the work you did and if you can do as many of these extra details as possible it would be great.

@BWOT It's a little hard, I would try to work on it with Voxel, but I don't know if it's possible to implement a map on the Server, not just the WP project.

Anyway, I won't be able to work on it for now, I will go in Great Britain for three weeks

Don't worry there is no rush, maybe there is a way to copy and paste it in bits?

@BWOT I know the command //schematica load and then //paste, but, you have to be designer to do that
and It will maybe make the server lagging

@slaMoria if you give me the world file I can work on it I know my way around in worldpainter

Maybe we can ask one do it for us... we can also do it in the morning when usually just you, me and mil are on .
