I really like the atmospheric and orchestral style you decided to go with! I also think you incorporated the electronic elements pretty well. If I had to choose a favorite track, I'd say Discovery because of the amazing introduction and unique usage of sounds throughout the whole song (that's not to say the other tracks are not as good tho, all of them bring such great compositions to the table as well!).
Overall I think you nailed combining electronic elements with such an atmospheric and orchestral OST!
That's all I have to say really, have a good day :D
