Very nice. I like how you got the background to have that noise and dust and scratch. One comment. You have two rivers running from the sea (or are those fjords?). Rivers don't actually do that. They can arise in mountains or in lakes, but they pretty much always empty in the sea.

Because of the unadorned nature of this base though, I could be totally reading it wrong.
Yes, I know, that this River is "painted" completely unrealistic.

That pseudo-river is just a test to see how this style of river drawing will fit the map style. (To be honest - I do not like it ; ) )

I've just forgot to erase it, before presenting it here. Try to ignore it. ; )

But I can assure You, that in the final version, rivers will be done perfectly and realistic.
