There seems to be some HUGE sound level gap between instruments that makes it feel kinda weird, dull and empty, acutaly it makes the piano sound kind of like a lifesaving (the track). I was so fking glad to hear that piano, because without that I would probably give you even worse rating.
Anyway I liked that trance add that went on at 3:36 and during the rest of the track.
that was realy cool and worked on me just like the piano did. But its a shame that you didn't fill the empty places with something similar.
