Blackthorne Seamarket: I always applaud the addition of sound effects, like running water and birds, to help submerge us into the actual setting of the game. This is a cute little track, though the harp-mandolin(?) combo feels less steam-punky and more medieval to me. (P.S. definitely consider using Musescore 4's new sound libraries! They are free and a major upgrade from the previous ones.)
Pine Wood's Valley: another lovely track! One thing I noticed with your flute melody is that it lacks a sense of contour: it sort of jumps around freely without a sense of start, end, or a direction along the way. For next time, always take these things into consideration.
Tenebrae Islands: One of my favorite so far: the haunting tritones, rain, and distant synths definitely give it a sense of mystery. To further create a disorienting and frightening atmosphere, perhaps you could vary the rhythm a bit? All the notes seem to change on the 1 and 3 of every measure.
Ardwen's Village: I love this janky melody with the whining dogs! Fun fun fun.
Nice work, and keep writing!
