That is a very nice layout mac ....
It has a much much better size & perspective .
Will you be adding a few shades of yellows & browns to portray the desert & mountains ?
Even as is , for my eyes its a huge improvement .
It's only the background that has changed - the size and perspective are all exactly the same. It's probably the effect of losing all the text and other details that make it look like there's more space.

Anyway, it is a bit too bland so far, though it plays okay. I do intend to get some topography into it, though I'm not sure how yet. And I think the sea is a bit too blue, as well

It also needs the rivers putting back in - that's the easy bit, terrain will be a a touch harder, but it's an excuse to play with Photoshop for a while. I basically used the LBM overlay as the template because that all lined up correctly and it makes it easy to select areas to work on which can be carried through to new layers. Anyway, I have some ideas to try out for restoring a bit of variety...
