I had been noticing the rivers more and more. I’ve already redone the main rivers to be less jagged. I'll also be adding minor rivers as well. There won't be to many additions, but certainly something. Sadly I have had precious little time to work on it. Perhaps this weekend I'll have some time to invest.
I've also added more roads, towns, and cities to make the world feel less sparse. I plan on adding a couple smaller lakes in addition to the minor rivers.
Thanks again for the comments!
