Thank you for the replies. This was my first attempt at doing a map on PS. I'm still not happy with the way the rivers came out and something I'm still playing around with. Moving the light direction I didn't think about though so I will have to try that and see how it comes out.

As for the forest, I used a layer effect to do it but I don't recall off the top of my head. It looks better zoomed out. When you zoom in it doens't look as good. Something else I've been playing with as well.
