@Oz I think having the Elves in the south, to the left would prove to be an asset to diversity. The wild forest is a good idea, curving around the mountains like a green aura.
Species would be great, I have a few in mind myself.
1- Human port in early stages of construction. 2- Human island undergoing population and development of agriculture etc 3- Area with highest Dwarven population. 4- Possible bridge crossing between islands, maybe a large ferry? 5- Southern swamp area?
