Main Theme (Lost): The upward arpeggios and suspended chords create such a floaty and thought-provoking environment. Contrary to the deep sadness you describe, I think that there is a gentle and somewhat blue mood that is also infused with a dose of awe that turns the overall mood into a content loneliness very fitting for being up in space. I love the piano - the reverb is so spacious and beautiful. Somehow you managed to make it so there is no clashing despite the long reverb tail. This is a very beautiful track overall - well done!
Moon Rock Waltz: Those shimmery plucks create a starburst sound we really wanted to make in our submission - but you executed it perfectly. The harmony in this piece is moving closer to the sadness that you describe, but the lively dance-like feel contrasts this and injects almost a sense of love into the track.
Ode to Stardust: Instant nostalgia for Cosmic Cove Galaxy from Super Mario Galaxy 2! I love the piano arpeggio style that has such a weightless cosmic feel. The melody is quite beautiful and the heart-wrenching harmony drives the longing sadness (contrary to despair) in deep.
Overall you have captured a very magical space sound that has a paradoxical distant intimacy. Bravo with your space palette which is very beautiful and well-balanced. This is an exceptional OST. Thank you so much for sharing!
