The 2nd map he asked for was "another map is a large open camp, backed up against a rocky cliff. There are pickets around the outside, with light scrub surrounding it. The camp is big enough for a group of 20" He also provided a simple sketch outline of the camp which my map closely follows.
Though I learnt a lot from my first attempt at doing a tree, and have a lot of new ideas how I want to do trees in future, for this map I just reused the same trees, bushes and textures.
The tents and fire are user submitted art from the dundjinni forums.
The third map is going to be rather different and, since none of these will see immediate use, probably not going to be attempted for another week or so.
