I like it a lot, few things first the piano at the start seems a little flat and boring might want to change the sound of it. Second, the beat change at about 1:08 felt repetitive, melodic dubstep should change often even if its between 2 or 3 different patterns. My ears wanted to hear the chords and melody to change with the faster beat. That way when you go back to the first beat the slow melody chords and drums sound crazy good.
Great start tho keep up the good work.
