Nice!
I remember having the midi and listening to it non stop and i find a pretty good equilivent to the original midi. If you would remaster not "remix" this song you should add some snare drums and tone down the electrical and only use piano with nice heavy and dark tone.
P.S. Enhancing the strings to something sharper and more frantic like would give this a very creepy theme.
Good Job!! 10/10 5/5
