I am simply swept off my feet by that beginning. The first thirty seconds of the song are probably some of my favorite thirty seconds of music ever. It's so well-composed, sweet juicy Jesus. I love me some flamenco.
Then you come back in at 1:05, a sigh of relief from the heaviness, and then BOOM they start working together again at 1:27. You have some excellent riffs in here that give a strong sense of imagery - like this is an island that is suddenly under attack, maybe.
Not sure how I feel about the near hip-hop beat that comes in around 2:22, it almost seems out of place. But the general feeling of this segment is very relaxed, like something got resolved, and it's still very well put-together.
Then we come back to reality with the main theme. You have amazing structure throughout the whole piece! Solid closure, too. Might have put a little more verb at the end there to signify that this event echoes in time, or some such sap. Really awesome work, overall. :)
