I checked out your map in the worldbuilder, I liked the idea of a center lowered area. However when I hear gorge I figure in my head like your area but alot rockier and with more variety in texture.
I really think you should work some more with this map, maybe try brushing the entrance to the Gorge, and perhaps even putting some more energy on the mountain.
A mountain in my humble view would be a bit more random and not all that round like yours is.
But anyways bottoms up.
Please continue with it and evolve and we can see the work republished.
