Great OST ! I really liked the coherence between your tracks. Holographic Design was very interesting, especially because it stood out from the rest of the ost due to the more electronic sounds. I felt like it fits well for a space theme, but I think I would have wanted more delay/effect on some background elements (like that square wave that repeats the same note throughout the song) for even more space-vibe. Nonetheless, it was a very fun ost and I enjoyed listening to it. My favorite track was Downhill Shore, it was lovely ! I really liked the peaceful vibe, the woodwinds and the sort of banjo for that countryside vibe.
Great job !
