Okay, I took another stab at it.
I have now mapped all of the rivers within the country I'm mapping. The landmasses to the north will get rivers, as will the southern region of my map, but I think I am going to leave those until the end, as they are not vital to the map itself.
If you guys could take another look at it and let me know how it looks as far as river realism goes, that would be great.
I'll be basing my hills, marshes, mountains, etc on where the rivers flow.
