Eerie and foreboding, with a touch of lament. I like . Excellent subtle use of the choirs. Also, good chordal support and use of the full orchestra.
The stuff around 2:00 is a great development in the short piece, and I think you should expand it, or at least have the orchestra crescendo on that last chord. The trumpet when it enters could lead that line more too, with stronger, more defined attacks (at least, that's how I'd play it).
Very cinematic! The held pedal on the end is really creative.
