So, real life finally gave me a few hours to play around with mapping again. I wanted to try to create an encounter map, so I took the principles from RobA's regional GIMP map tutorial and applied them to a smaller scale. One of the maps includes a grid and transparent foliage for the trees, so as to better serve as an encounter map. The scale is the D&D standard of one square = five feet.

The other map doesn't have the grid lines, and has some subtle depth added to the foliage.
