I loved the opening! Very pretty, and this particular chord progression fits that sense of hopeless running you describe in the story. The various solos for each instrument were so cool! I loved how you upped the tempo-- great climax! Beautiful vocals at the end-- something about the solo voice really added to the forest-ey feel of the track.
My only advice is this: having the same chord progression on repeat the entire time can be limiting. Try to experiment with the recurring motifs another way, and let the harmony be more flexible. Still, a very beautiful and well-mixed track!
