I like the mood and the overall sense of progression. What's with the click at the beginning of the track? :P
I'm very curious: what orchestral elements did you use, exactly? I thought you meant orchestral instruments, but I didn't really hear a lot of that.
The trance vibe works well for the most part. I think the choice of chords and instrumentation fits the mood I get from the artwork and the progression is fine.
I notice that in the few instances where there seems to be a melody, like at 1:04, for example, it feels like it should be using the pentatonic scale, but there's very clearly moments where non-pentatonic notes are present. Perhaps it wasn't your intention to use the pentatonic scale, but to me, the non-pentatonic notes felt really out of place in the melody that otherwise would have fit to the mood and soundscape comfortably.
Honestly, I felt like it could have used a bit more bass. Personally, the instrumentation felt too light and thin. But that's just me. Overall, I think you took the right approach for this theme and I thought the structure was great, as well as the melody (for the most part). Good entry!
