Wow, great collab you two !
I too can hear a bit of Enya in there, it's very ethereal and atmospheric - but with more of an edge! Those drums and the sharp synth sound in the left of the stereo field are awesome !
The spoken vocals are a very cool idea, so original. And the rest of the vocals are sung just beautifully.
I think you managed to create something really special here. Love that atmospheric sound.
One point of critique if I may: Sometimes the vocals seem to stop at one position in the mix and then continue at a different one (Maybe a different track in the DAW, that has different settings concerning panning, volume and reverb?)
Example at 0:49.
I found this to be a bit distracting from the songs flow.
Only one detail in a great song though, keep it up guys
