I like Larksong however when I first read it, I read it as Lakesong which imo also makes for a really pretty foresty town name too! Mosspine flows really nicely and fits the theme perfectly though, as do the other names too. But as soon as I think Mosspine I think of a lush forest, thick with trees. But I do like larksong the best, I will say. These are all really nice names!
I really like Duskfall. It reminds me of dusk during the summer, and how peaceful it is. Crickets chirping, fireflies around, the sun setting, people getting ready for bed. It sounds peaceful.
