Very pretty song. The vocal is muddy. I would try to brighten that up a bit.
As far as arrangement, and I mean this in the nicest way, it's too long. I get INTRO VERSE VERSE CHORUS VERSE VERSE BRIDGE CHORUS INSTRUMENTAL CHORUS. Don't know if these are the names you gives the sections, but I would get rid of a verse after the first chorus, and the instrumental. Make the chorus after the bridge the last part of the song. That should get it down to 3:40 or so. If you're in love with the instrumental (which is lovely, by the way), put it after the first chorus and then go straight into the bridge, chorus and out.
Good job!
