It definately sounds good
and your instruments are powerful. I like the way it builds up at 1:20. I guess adding some subtle melodies or drum patterns (in addition to the ones you already have) that evolve before the drop would help. I don't know so much about electro house, but I guess it often takes in new drums before the drop happens (I'm not sure though): The sidechaining is well done, how did you do it?
