Well, I can tell you that the Textures are from Omnisphere, & the Drum Loops beginning around 2:36 are Drum Sample Loops. I think that they are from a Wonky Loop Collection of sorts, if I remember correctly. I then added a lot of reverb too. I was going for a kind of a mixture of feelings, like Ominous, Strange, Mysterious, yet still Grand & Beautiful all at the same time. Glad to see that it seems like you enjoyed it!
