Wow, that was a really hard vote! Lots of great entries this month. I ended up going for:

professorthunder: This just feels like someone actually stopped there. The detail is incredible, and it's very well executed.
yandor: I can totally see this in my game. I really like the cut-ins as well. It evokes the kind of campsite where someone's singing -- probably badly.
jaxilon: I love the spooky feels-safe-and-defensible-but-wait-what-was-that feeling this gives.

Off to go spread the rep, there are a lot of deserving folks this challenge
