Good, but mastering issues are present.
Perhaps you put a longer attack time on the string synths at the beginning, but it certainly seems to me that the bass drum at the beginning overpowers the rest of the instruments. The rest of the song is definatley nothing I've ever heard from dubstep on youtube. The progessions you use on the rhythm is good, and it fits the title very well.
The piano during the main part I can tell is the melody, and it's a good melody, but it's too quiet, and the rest of the instruments are overpowering it, especially the drums closer to the end.
