Agree a bit with the off-tune comments below, but they're not that bad. You *could* say they were intentional depending on what you were going for with the song (if you were going for a haunting kind of feel). They're mainly in the intro and then the replay at the end.
One thing that bothers me is the staggered feel of the notes. Sometimes it seems like the left hand is just playing the same note repeatedly for a while and the pace never really changes, but again, that really depends on what you were going for.
