The Highlands - Fantasy Map Uncolored

This is the map for my groups D&D campaigns. I decided to upload it before i fully finished it so they could use it (We take turns DMing). Its a conglomerate of different terrains on a flat earth floating somewhere in the Elemental Chaos. The outlets between them are areas where the ocean runs out into an endless water fall. I dotted the map with towns and points of interest, including 3 human kingdoms, 3 dwarven citadels, and 2 elvish cities. the areas are - Tundra, lush grasslands, Mountains, Ancient forest, Mordor like deadlands, a half swamp/jurrasic park continent, and a desert. It also has an Underdark but i havent sketched it up yet; itll be the good ol' fashioned Underdark - tunnels, mind flayers, drow, the works.
