We have choosen the first version, but there are some things that need a little bit more work;
Coast and rivers should look more natural, softer. Currently edges looks too hard;
More versatile terrain, currently it's too flat, so a hill here and there would look better, especially in the rhodoks part of the map;
Some hills are too high, make sure that hills don't exceed the hill hight from native.
Those are some things that need improving, they are minor but it's the details that make the difference between mods.
