Hectic couple of weeks at work! But it seems I'll have time to finish this one! Hopefully pulling an all-nighter today!

Thank you for your comments, guys!
Bogie, I'll fix the rivers. The "lakes" were actually just badly painted terrain that looked like that when I applied the "stroke" effect on the layer. I kinda liked how rough it looked, but you're right, they look like lakes, so I'll probably get rid of them.
