I quite like how the main land are defined with their darker tan coloring and bolder borders, but consequently the difference between water and the outlying land is too little. I'm also having a hard time telling if the tan lines that cut through the large island to the right are paths or larger rivers... Either way, I think some of the interaction between elements can be cleaned up for more clarity (if a river cuts through the mountain, or if that's just an accident, etc.). Keep it up!
