It has an interesting modal sound to it... are you familiar with modal harmony? If not, it might be something interesting to explore around with. It almost has this non-western tone, like one of the Hurrian Hymns, such as the one utilized (with no relevance) for the theme of Charlemagne for Civilization IV (https://youtu.be/wqjgPBITiX4?t=83 or https://youtu.be/wqjgPBITiX4?t=183). Notice how the non-western non-standard scale steps and substitutions really color the sound of the piece. (if you're interested in learning more about the Hurrian Hymns, check out this: http://individual.utoronto.ca/seadogdriftwood/Hurrian/Website_article_on_Hurrian_Hymn_No._6.html - scroll down a bit for the musicy part).
I felt the use of effects and synthetic tones made the hybrid sound quite pleasant. I would recommend perhaps a bit more reverb on the choir and putting a bit more distance between the choir and the listener; right now it just feels a little close in the mix.
Compositionally it is quite nice. You have some good use of contrast. For even more, you may even want to consider some modulation or temporary tonicization in the middle... some tonal wandering is never a bad thing for audience retention.
