Running off to Adventure: It feels grand but light-hearted, with a hint of etherealness to me. I think the drum panning is cool and they have nice rhythm, I feel the drums overwhelm the other elements though; They could be lower in volume or more centered(not complete center though) if that volume is what you wanted , but I'd like to emphasize I really enjoy the rhythms you went with in the drums! I think the piano and flute parts compliment each other well too, and the triplet usage is especially nice!
What Lurks in the Dark: The guitar is very nice sounding, and to me the repeating nature of its melody gives a feeling of "despite the uncertainty and fear, there is something to guide through" . The strings, pianos and drums all add nice depth to the track. I think you could have been a little more adventurous in the composition given that it's meant to invoke uncertainty and fear. One example is, I feel it could use more inconsistency rhythmically(not often but just a little bit), or added silence, to give the listener less to hold on to, but that's subjective and mostly specific for this jam, I still think you did nicely achieving the feeling you wanted to go for, especially with ambient sounds in the beginning and the heart-racing piano.
The Journey By Your Side: This song is nice and heart-warming to me, I think the composition is great in this one. I like the two flutes you've used here, it is like they are speaking to each other. I don't have any criticisms here that others haven't already mentioned. I like the inspirations you used for this track as well!
Overall, I think this is a really nice soundtrack, and it explores a nice variety of emotion. Nicely done!
