The map is supposed to be from a PCs point of view. A map a mapmaker would make in one of the larger cities of the north.
Full Disclosure: I am a horrible artist, so this map looks much better than anything I could ever draw.
I personally prefer the more-detailed map from the 3e FRCS.
Both the South and the East appears to be truncated. (Chult and Thay are cut-off.)
BUT all that is trivial because...
This map totally belongs on pg 2 of an Atlas of the Forgotten Realms, facing a page-full (p3) of text with the header "Overview".
If you have seen maps of the medeval world, this map looks in line with those.
Again this is supposed to be a map made by a map maker from a large city in the North, maybe Waterdeep or Neverwinter. So it is not the detailed map for a DM, it is a map of what your PC might have in their pack.
This map was shown as a preview in Dragon + for the new Sword Coast Adventures book. The map I posted it is from that.
I love it. Its dark and gloomy and its coloring is limited.
It's a good start. Gives players an overview of the major regions of the Realms without getting into heavy detail.
