i come to listen every now and then :D
Overall a solid song. The part from 1:00 onward is the strongest. Very nice sound, good harmonies, surprising 7th chord (I think? I know what you did there, I just don't know if it's called that).
You are kinda right about the post 2:00 part being like another song. If you make the chords return to the ... uhm, tonica (in english too?!) you know the main chord, every now and then, you would draw a stronger connection between the parts.
My main complaint would be the bassline in the starting part. You should scratch or redo that, it's harmonically off, but not in a good way.
Full score for sound, points off for harmonics. I'd like to hear this as a refined complete track though!
cheers!
