A few comments on your start.
- Rivers rarely flow from a lake in more than one place. The inner lake has 6 rivers flowing out to the sea.
- You added a lake to the lower section of the map. While this is not explicitly stated in the rules, note that some people may disqualify your map from consideration in their voting due to this. The Community Leaders won't disqualify any maps, but we do make sure before voting commences that the rules of the challenge are restated.
- it looks like you have drastically changed the course of the river on the mid right bay as well as the one from the upper right lake inland.
