A welcome break from the several dungeon maps we've had recently! What's more, this map showcases an evolution in cartographical style! Well, perhaps not an evolution, more an experimentation. I've been struck recently by some of my more skilled peers and their use of trees-for-the-forest style; it really adds texture to what would be pretty empty space on a black-and-white map, and allows more freedom in intermingling various terrain features or showing feature density.
That said, from a creation point of view, it's much more time-intensive than the lollipop clouds of before. Hills and mountains are easier, sure, but my goodness do forests take a much longer time. Still, I think it's worth the effort, and I'll be exploring and expanding on this technique in the future.
