Its a good arrangement and production but not the sort of music I listen to so its hard for me to be constructive here. I feel the things I don't like will be liked a lot by others as its only personal taste but musically I can hear nothing wrong. The vocals are of your usual impeccable standard, some fantastic harmonies really lift the chorus. Nice breathy sounds, what did you use there? real breathing or the new NI instrument they are plugging at the moment? The breakdown is on now as I type and that has grabbed me. Bass enters nice. I good arrangement here coming out of the bridge/breakdown.
Sounds quite epic in places, Its all you wanted to achieve.
