I've been learning to use Dungeondraft, with Forgotten Adventure assets, and decided to make the most generically applicable map possible. It turns out, it's quite good at outdoor terrain!
The ground textures blend together well, you can scatter stuff around, and it's easy to create the sense of an uneven, hilly terrain.
In case Reddit decides to ruin or compress the image (I'm already seeing it way more washed out than the original), here's a download link.
EDIT: Jeez, Reddit, what the hell? It completely desaturated the picture in the upload.
