The Daft Punk synth at 1:00 is niiiiice.. I just hope it's not a sample. >_>
Mastering could really use some work, there's a lot of extra frequencies that don't need to be there. Try compressing your choir and not cutting out so much of the mids.
Besides all that, this is pretty damn original. 2:05ish, you got some harmonic problems. Also, at 0:50, the super reverb on your violins is messing with everything else. Lower the attack and cut some reverb during that section, i say. :p
Weird transistion at 2:55. The mix volume of violins and the harpsichord synth is kinda off, too.
Cool overall though.
