I on the other hand have to say that, for the purpose of the map (aka a book map), i do think the first version will serve better. As a long time fantasy novel enthusiast, i have to vote for version 1 (just fits better with the flavor of map vs the in-world "believability" and i also think in a book the version 1 map will be better readable).

Now that is not to say that the map will not look awesome with this style. I think it comes along quite nicely. The shading is top notch. But i agree with Texas Jake that the ridge lines are too strong.
