A mostly deforested valley is a great visual right from the start. I liked the conversational tone you used to present information. I recommend flipping "The Saddest Village in the Barony" and the "How to use this Adventure" sections.
The adventure has a great personality, I like the themes explored, and you did a good job capturing a run-down feeling in the town.
I liked the layout of the Temple and the Caves/Cellar and that they were not overly dense. If I were running this I think I'd try to add a few set pieces or interesting moments in some of the rooms.
