The intro is very reminiscent of Kingdom Hearts Re:Chain of Memories and Kingdom Hearts II (especially Castle Oblivion and The World that Never Was). These are dark areas, and the music has hints of subtlety. What would be beautiful here is if you had a little bit more in the way of dynamics.
Then, come to 1:00... oh man, once again, I love those drums <3 There are chords that don't click together with the melody, so a rewriting of these chords is due. Remember, it's your first song, but it can stand to be better -- so don't be afraid to show it in all its full glory! Rewrite those chords -- inversions, what have you -- and trust me, you'll have a winner.
That syncopated violin melody around 3:00 was beautiful, but it could stand with a bit more of a counter-melody. A melody from, say, a solo cello, backing it, with solid chords.
Unlike the last two I reviewed, this one... I could already sense the good in it from the minute I started listening to it. Again, knock out the kinks, and you will have a winner.
Because this piece is about the old battlefield, where his friends, and finally, the hero, die... allow me to ask you to look up a clip on YouTube. "Kingdom Hearts 2 Final Mix Secret Ending". This illustrates the point rather well. Watch the scene, listen to the music, absorb the atmosphere... and remember which points in the piece you want the tension to rise and fall.
