I'm seriously liking this one. I loved the way that the song developed, and really appreciate the fact that you reduced repetitiveness to a minimum, bringing it close, if not together, with actual classical orchestral compositions (in my opinion, that is).
This has, however, also resulted in a sort of down-side- namely the fact that sometimes it seems as though notes were just randomly tossed on upon another in order of creating more versatility (unless this was your intention, or I'm actually imagining things :P), but this isn't necessarily a bad thing, could just be something that feels weird upon the first few listens, and then you get used to it.
The choice of instruments you have made for this piece is very satisfying, as well as the percussion, apart from the snare which sounded a tad too artificial at times, but not enough to ruin the overall feel of the song. The way you intertwined the strings with the wind instruments is really good, and gives off that classical two-voiced "conversation between instruments" feel.
As for the mood of the song, it features an interesting development from a sort of ridiculous serious mood which slowly progresses to become more of a heroic, yet still serious piece. My impression of the song would be an old 19th century general who is preparing for the battlefield - sure, his enormous mustache might seem silly at first, but after prolonged observation, you get to respect his military genius and realize he's much more than just that.
Bottom line: really good, and requiring only minimal (if any adjustments). A very nice piece of work that I would without a second thought suggest to a lover of classical music, and most certainly a heavily under-valued song when it comes to the score.
