however if the bass is loud enough then u dont have to lower the levels on the main lead/ melody. but yeah good job maybe instead of a sudden level drop u could have it slowly fade in. :)
these synths are really cool, and so is the melody. but this is more techno/dance then dubstep. but im liking the build-ups. what u need is intense bass. to make a good drop u need the drums and melody pushed back while the bass fills up the drop. but i really love the synths and drum work in this, and i think you are making good progress.
