I like the intro as well but the dirty bass after the 'drop' is a little too dirty imo. It really changes the whole feel of the track from a haunting atmospheric thing into a murky reese'n'bass thing.
The synth bell sounds great in the intro, really haunting but combined with the dirty bass work it sounds very off key.
The loudening drum part in the end goes a bit over the top for me, had to really reach for the master fader with that.
