I like the atmosphere and the progression of the piano. Admittedly, I thought the "ghosts" sounded more like melodramatic gargling. Maybe it would help if you tried to hide them a little more in the mix by increasing the wetness on the reverb. I tend to think that indistinctness is creepy, and I think creepiness is what you were going for here. The piece also was a little more fast-paced than it should've been in order to maximize the drama and/or ghostly qualities of it. Also, I thought the delay effect you added at the end of the piece was kind of a lazy way of concluding what was otherwise a very flowy and well-balanced effort. I've been pretty tough on you in this review, but fortunately you might find that the bulk of my criticisms are relatively simple to address. Otherwise, keep up the good work! ^^
