A village far away - Love the bouncy feel of the guitar(?) and bongos(?). Nice melodies! If you can, maybe add some expression automation on the violin vst.
Song of adventure - Very nice folk flute sound, especially all the bends.
A moment to gaze the stars - Really strong melody and accompaniment in this one.
In ancient ruins - Nice to hear a contrast in mood and texture. The whole track is really creepy but I think you could pace the tension a bit more. Start a bit smaller, and get even bigger in the climax, maybe using a bit more cinematic strings and percussion.
A legendary song - Very exciting track, great use of time signature to build tension. I agree that there should be more low end pushing the track forward. Some big percussion sounds and low strings. Auxiliary percussion could help hear, like an ostinato on wood blocks and/or shakers.
A rowdy evening - Great mood to finish the soundtrack on, feels like a heartfelt telling of an epic tale. The drop out at 1:28 could have been a bit more delicate.
It's not super clear what the medium of the story is meant to be? I'm imagining it could be an animated short film, or a linear story driven adventure game. Love the sound of the ensemble, especially with all the folk articulations. I think maybe there are just some reverbs that don't match, some instruments are dryer than others. I would also suggest adding an upright bass sound to some of the folk ensemble sections like you do in the final track. The free kontakt one is pretty good and has a fairly dry close mic sound.
Great stuff, thanks for sharing your OST!
