Thank you so much for the compliments, they are much appreciated!
In the main theme i used a cello solo as main instrument (replaced later by a bassoon) and to create the textural sound i used a Kannel (estonian instrument similar to a harp) for the arpeggios and a guitar. The other particular sounds are made using strings in an aleatoric way, mixed up sometimes with choir and sometimes with some granular and noisy synth patch that i designed on arturia pigments☺️
