This is absolutely delightful! It's got a lot of variety in terms of how the PCs are challenged, from wilderness travel to roleplay to moral dilemmas. And you nail the slightly cozy, very creepy, entirely whimsical feel for the fey. Also, I love that the Rain Shepherd is so dang grumpy and unpredictable, that feels very true to real life. If I get to run this at a table I'd sneakily use my phone to play Don't Starve music when the bog lurkers approach from the darkness.
The fantastic art and layout and general style is also a huge bonus, and I love that you photographed the physical components too! Great work all around!
