Very cool song. I like it a lot. Cool harmonies. I too, think the crashes could be tamed.
My only other thought is more about the composition/arrangement - where the song changes up from the waltz to the 4/4 beat (happens a few times throughout), I'd like to hear the guitars (and bass, etc.) change up more too. As it is, the drums change, but other than the time sig, they are played fairly similarly, so at first listen, it almost seems like a drumming mistake. If everything changed (play more staccatto guitar strums, for instance), it would be more apparent that it was intentional, and it would seperate the parts more. Or maybe there needs to be more of a crescendo (of some sort) to signal the change tween 3/4 and 4/4. I dunno....I really like it, obviously, or I wouldn't have spent this much time thinking about it....
