Those mountains are outstanding; did you draw them?

I like it!

Like Max I wondered at the river sources; I know there's that big marsh in the center of the island. Shouldn't that river system that flows west out of it instead head east or south, where it doesn't have to go through/over the (presumably) higher mountains?

Nice choice of fonts and good colors. I like the compass as-is.

Also, is there a typo in the title? Is it Rocix or Roncix?
