I like the new rivers, that was one thing I realized first in the first map, too.
There are quite a number of big river splitting but it works for the Fleuve (because of the mountains) and Sirthenn/Nunên (because of the huge lake / small sea). Not so much at the Linden/ Rivtère Verte. Just from looking at the map, I would expect the Rivtère Verte to dry out. If the river sprung further inwards in the Vala Ethennand then approached Vêlyr from the northeast, just to turn southeast before reaching the city, however, it would be possible, that an industrious Duke would build a channel through the Vêlyrn ridge in order to connect Linden and Rivtère Verte. (Sure, this would have to be maintained and controlled in order to not run dry or produce ugly floods in the wrong areas but think of all the taxes to be collected, if the small villages around Lac Vert could ship their wood directly to the mines of Thrôrianor and stuff. )
Coastlines: They are interesting. I like that, that definitely makes opportunities for some great political constellations. Also looks plausible, except: Amsor. I can not really imagine how this came to be, landmasses don't just shatter apart. And oceans don't just decide to cut some straits through a continent. A single crack in a landmass/ocean strait like through Per Véllénir is easily explained but those are like 6 different breaking lines in Amsor!
Possible explanations? First of all, of course the fist of an really angry God. Yes, this could really well be, what a countryside could be, centuries after the continent has been smashed by a mayor God.
The second guess would be a really unlucky friction zone of 3 tectonic plates. This is probably the better explanation in all but the most high fantasy settings but the logical consequence would be, that this area is an earthquake hell and probably has 3 different words for Tsunami. ... Okay, thinking about this, I like the coastlines there, too. I -as your hypothetical reader- just get curious WHY it looks that way, so you better have an answer.
Mountain ranges: Again, just one point here: Why the Paines of Moriag? Especially in that shape, I really can't think of any reason, how this could have come into existence except for a less angry and more tidy God with a huge plane (the tool).
And last, forests: Well, those seam to be rather randomly placed, are they?
How do forests happen anyway: Air goes over sea and picks up some water. If the sun shines hot and the water evaporated, it takes a lot of it. Then the wind hits land and needs to go up because of the rising altitude, rising pressure and some stuff I don't understand happens but the result is clearly: rain. Especially rainy, if the moist wind hits a mountain range (consequently, on the wind shielded side of a mountain range the wind is rather dry). And since weather is unpredictable to a point, there is a chance of some rain some times, wherever there is dominantly moist air, even if the land does not incline a lot.
Thus, the forests are mostly weired, it's not just one. Most obvious offenders are:
- The isles de la perdition: water around them everywhere, the Septentrinal forests have no reason at all to stop at the sea, those isles should be thick of vegetation.
- The Figèe forest between the Titan's break mountains and the dunes of Ocreterre: If there is south wind from the Sablonnant ocean, enough of it would come down over the dessert, that it's not exactly a desert and if there is dominantly north wind, it would rain itself out on the north side of the mountains, not on the south side (This is the only instance of forest where it should not be, other then that, there should overall be more green).
- The autonome forests in central Amsor. Whatever wind flow makes trees grow there, it should provide good rain and temperature for forests for at least a quarter-circle shaped part of the shattered continent. That is, of course except for magical effects. Likewise artificial forest cleansing could result in something like that but seriously, on this scale your world should have at least around World War 1 tech level for this to be plausible.
Overall, the map has succeeded on the most important test: If you (or me) can zoom in on 5-10% of the map and the land features create a number of ideas for stories of regional scope, then it is good.
