Orchestral elements here /do/ sound nice. It's the guitar that's lacking. Doesn't sound like they're double-tracked. Kind of hiding in the mix. I'd probably recommend RealEight in place of whatever you've got here. I can tell 2:05 is not a synth. If you didn't commission someone else to record that or play it yourself, I'm not sure why you would chose to synth your rhythm guitars there. Not a serious detractor but does take off a good half star just for guitar mixing/synth. You could probably have gotten away with slapping an amp on a dry cello with a pick sample midi vst the keep the attack clear.
That said, wonderful writing. I found the only thing this piece really lacked aside from what I've already mentioned is some compression to give it the power I know you want to convey.
