Beautiful voices, great harmonies, chucking guitars, great piano accompaniment, cool synths, nothing not to like but the drum sound in the louder parts.
And maybe the guitar/synth/whatever-it-is solo could have a sound more reminiscent of U2/Edge. Warmer.
But that's nitpicking.

I love it.
IMHO your best so far.
Great melody.
Catchy as hell.
Could be a hit!
