Thanks for the feedback guys! The night I posted this I actually saved a copy of the PSD and started tweaking the text to be simple black with a lil subtle white glow behind it for contrast--no garish stroke outlines or anything. Font-wise, I agree and will prolly fix that too next.

I started reading forum threads here/learned about river behavior AFTER I had already started the lion's share of the work on this, but the good news is I have the rivers all on a completely seperate layer and can remove/edit them non-destructively whenever I want! The only issue will be tweaking the contour marks/shadowing/elevation on the land around it...but those are all ALSO on seperate layers, so it won't be a huge pain in the ass!

Any particular resources I should check out as for river rules? I know the basics (rivers flow downhill, rivers converge when heading towards coastlines, etc etc) but any guidance would be super helpful!

Thanks again for the critique and the kind words.
