nice!
Hey hey, really cool song. Just a few things I would have done differently if I found myself doing a classical song starting with the dynamics. Real instruments change their dynamics over time expressively. Dynamics is just a fancy word for amplification over time. There were a few crechendos in here, so I know you what's good. Just playing with the note velocities would create a good amount of terraced dynamics, but I find that it's more effective to automate shifts in dynamics instead. Of course you could go on to say that a song about a tyrant works better with terraced dynamics to give off a sort of marching dictation to it but I find that rhythm has a better effect than dynamics at expressing that kind of vibe. You're probably familiar with Nobuo Uematsu's One Winged Angel theme but go look that track up and really listen to how the instruments effectively change their amplifications over time to create tension. Sometimes the composer even uses syncopations that really create tension. Such a good fucking song.
Panning: I have trouble telling where there's panning if it's not really obvious, so I'm sorry if you did have some panning in there, but perhaps more pronounced stereo imaging would have been effective. Stereo imaging emulates live acoustics so it can help eliminate the digital burden of a mono mix. It also creates the illusion that things are louder than they actually are so you can turn the levels down on everything and have a cleaner mix in general.
Harpsichord: I'm really anal about that instrument. There wasn't anything wrong with using it. I'm just not a fan... you also used it in conjunction with a piano. Nothing wrong with that either. Like I said, I'm just really anal about it and in a typical classical piece, the two instruments would not have been heard together. This review could have gone without this harpsichord tirade :P
All in all, this song will work great in a flash and it's really cool man! The melodies are all really interesting and the harmonies work well together. Keep at classical composition, you definitely got some skill here :)
