Great soundtrack ! Love that leitmotiv, could use a little more variation, but it's already great ! The ambiance is on top, really immersive, we feel the coldness and the spatial environment in those tracks especially with the reverb, the piano, the overall slow tempo of the musics, the synths...
My favourite is Awaken, you handled well the parts of this one, the piano is beautiful, it plays the leitmotiv, but sometimes it stops right before, then it plays in a longer version and you add more layers to it throughout the music. The ambiance is great !
