I personally think that the transitions in this song are great. They have the right amount of white noise and the trancy lead is really fitting. Unfortunately I don't like the main lead and middle part too much. I think there is not enough variation after 1:05 with exception for the transitions, which are still very good. I would like to hear more going on in the main parts but the introduction as well as the transitions and end are great.
Keep it up :)
