For a version 1.0 it’s impressive, for classic purposes the voice timbre is OK and the Latin is intelligible.
And yes, the final s phoneme is over-over-emphasized. 
I didn’t touch the key editor, there are just the dynamics and some adjustments of the base volume.
Woodwinds, trumpets and organ are VSL, trombones, timpani, and strings are NotePerformer
Unfortunately I couldn’t upload the file, the size is too big

Edit: After listening to only the choir tracks I noticed that the male voices are louder than the female voices and the alto (although the same “voice”) is louder than the soprano
With these mixer volumes the balance of the 4 voices is more natural, especially the rather homophonic “oro supplex” part.

Not bad! A slight hint of joyful communist propaganda, but it’s quite usable for testing things out. Thanks for posting it!
Yeah, can you get the Men to stand a bit further away…? 
They’re a bit ‘in yer face’.
I too noticed that the solo voices weren’t balanced equally: I had to turn the Soprano up a lot.
Here’s the second attempt: The soloists. It’s also from Mozart Requiem, the Recordare
The voices are: Violetta for soprano and alto and Jon for tenor and bass. In my opinion they match best for a classic soloist quartett.
Assuming not to be used for music production to replace humans but to get an impression of the music the result is quite good.
Again I balanced only the volumes of the voices, nothing else.
And regarding of some vibrato of the girls I remember performances of the requiem with famous (dramatic) singers who had at least such an amount of vibrato, however everything else sounded beautifully
