The mountains look much better indeed. Some suggestions:
- Make the back side of your mountains visible.
- Randomize the tile direction of your coal fields.
- Your map has elevation, but all on large scale. This looks good on a distance (like the screenshots), but less good when zoomed in. Try to add more variety to your elevation by using smaller brushes (even the smallest brush).
- I see you're having a hard time to fill up all that empty space. There aren't much maps that have so much space, so I can't give you very good examples, but at least look at Ambushed and see how they did it in a very easy way (that still looks pretty good).
- Your forests are no real forests, they're more like 'a tree here and there'. Try to make them more compact and do not use too many different trees (do not mix fir trees and other trees for example). Also, it is not compulsory to place your trees on certain tiles, it will look better if some of them are on the grass. Otherwise it will look artificial.
That's it for now I guess.
