Treetop Outpost
Fistfuls of falling damage is always a good way to kick up the tension a notch or two! If you support MicroDwarf on Patreon, you can see the whole encounter's worth of ways to bedevil your players!
It took me quite a few attempts to get the perspective on these tree trunks right. Eventually I figured out that the distance the trunks were separated in the air should be proportional to the distance they were on the ground, using the same ratio as I used for width.
Seems obvious in hindsight, but hey! This is an adventure we're taking together! Mistakes will happen. At least my mistakes won't mean falling 50 feet to my doom - I'll leave that to your characters.
I'm glad the tiling turned out as well as it did, I was worried it would look too much like stone. Nevertheless, it's a nice, clean look, and it will help all the mini-masters out there plan their next move!
