Very well done.
I like the simpliness of this track. Not too much going on, which is in this cas a good thing. Because it´s so empty, it gets scary. Nicely done.
I really love the EP/bell thingy melody. It is the base of the whole track and it works great. It is simple and repetitive (with little variations). Both work out fine.
Though I feel like i'm missing something. This could be awesome for some kind of spooky trip in a game or animation, but for a full track it seems unfinished. I'd add an extra part with a big epic orchestral drop. Some wild violins and maybe even a brass section. At least you need big timpanis or other kind of deep, large percussion. If you manage to add the EP also in with his chracteristic melody of this tune, it would be awesome. This would really give an awesome edge to this tune.
