Hello all,

Attached is the original map I made using RobA's and Arsheesh's tutorials on regional maps and forests.
Im currently working on a version two of the map and Im curious as to how to go about achieving an effect.

Explanation: The original map shows a swampy, moorish area known as the Felglas March. For the first go, it came out pretty good. For my second version I would like to show the lowland area AND the highlands surrounding it. Using Robs excellent tutorial once again quickly gave me a nice highland area. And Ive used the Free Select tool to draw out the area of the lowlands. My question is, I suppose, would anyone have any tips on simulating a sunken, swampy area from the highlands?

Any assistance is always appreciated.
