Awesome
There is no other word to describe this piece other than awesome. This is incredible. The technical aspects of this one are as close to perfect as you can get them. The aspect that really sinches the song is the lone string instrument solos at 0:19 and 1:12. Single instruments playing slow, gradually rising tunes really puts one in the mindset of something epic to come. Another thing that I like about this song is the very subtle choir in the background of the song. For a piece like this, the choir needs to be in a supporting role or it can overwhelm the orcestra, which detracts from the song. This hits it just right. The final element that makes it perfect is the lone woman's voice towards the end of the song. My only complaint about it is that it is over so quickly. You might consider doing an extended version.
What I see for this piece is a towering fortress burning in the predawn gloom. An army covers the land around it and warriors battle in the inner courtyards. A lone warrior stands in the keep's entryway, waiting the moment to join in the battle. Then, he draws his sword and pushes open the door to the keep. At once, the sounds of battle fill his ears and the horror of battle is laid out before him. He rushes into the melee, striking as fast as he can weild his blade. Warrior after warrior falls to his sword and he is soon into the outer courtyards. Then there is one last blow and the scene goes black.
If you were to extend this piece, that scene could continue on for many more paragraphs. Oh well, a very good job and straight tens for the Maestro. Keep it up.
