Nice full sound. There were moments, especially near the beginning, where I could almost hear the seperate sections. I hear a lot of choral work (do sound for a local chorus) and it takes a lot of convincing for me to hear anything but electronics in a sampled choir. This, as I said, came close in spots.
Forgive a tiny rant. It seems so strange that we no longer accept a synth "string" patch, insisting on writing out the divisi and knowing the ranges each section can play: but most sample libraries continue to treat the chorus as a monolith. Where realism comes in for me is hearing the character of each section clearly as they sing their individual lines.
there is something a little unsettling about the cadence at the end of your fragment, sounds both too final and not final enough -- maybe the funny off-beat but not moving bass line F to G, then held G under the major triad?
