I'd say, mess a little more with sea land borders, maybe take some land(especialy from the blight), add some ocean and add more variation in vegetation on blight and snow.
i really like the jungle down south, but one of the small cities has to go, maybe turn it into a townsland, perhaps the city up north could also become a stronghold?
also turn some cities in old mesh Heen into townslands or strongholds.
Beluaterra should be different and allot smaller.
Don't you think?
