Really nice writing on this piece, and good atmosphere, even making those synth strings work.
Couple notes. On your reverb, that long tail, high wet signal is okay for single instruments, but if you intend to use it in an ensemble I would low cut it to 250 hz or so. It's getting pretty boxy sounding in the mix by 1:20. Textures here are sounding pretty good. I would back off a little bit on your droning bass at 1:40 and emphasize the highs on that pulsing bass in the right channel panning around.
Even though the piece mostly stays in the same vein, and I was expecting something much longer given this development, you're quite talented at atmosphere.
I do have issue with the fade out. With the ongoing nature of the piece, it makes it feel like a preview more than a theme. I would just have made a second intro with that synth and ended on a high i chord.
Thanks for coming out to NGUAC!
