I'm liking this track, but bothered by the fact that something is waay out of tune. Fletch mentioned the keys, but I think it's the reversed pad that is causing it. It's out of tune and making the other melodic components sound way off once they come in.
I'm not sure if this is really a qualifiable test, but I held my guitar tuner up while playing the intro and it was clearly registering the notes but everything was almost a full 1/2 semitone off (sharp).
I bet if you fixed that issue, the track would go from good to amazing.
