I love the style you based the track on, the eerie, classical style piano however I felt the dubstep could've been approached differently, I personally don't like all the high frequency synths used in the main chorus section, however the arp is very nice. I think this track would've benefited it more if you made it more minimalistic like the old dubstep vibes,rather than the punchy "in your face" style of dubstep you was going for. In relation to the intro I think It would've been nicer if you used more deep, sub heavy bass sounds that the wide, sustained bass synths. I also felt your drums lacked the weight which could've been fixed with tidier EQing and compression. overall its a nice track with an interesting atmosphere that could've been aproached differently
