Metals, huh?
Let's see how this works out...
You start out a little simply but build things up quite nicely. Your melody's nice. You could try changing things up throughout the song, rather than generally sticking to the same instruments and changing little in the melodies and harmonies. Your sound effects are a nice touch, and your pad, while a bit weird, is pretty good. Your percussion fits the song, though you could have made it a bit louder.
Overall a nice song. Why don't you stop by my audio page sometime and review my latest, Nova? =)
