The intro, I will honestly say, I don't know how well you EQed it (it doesn't sound so at 0:29 onwards), but it really gave me chills down my spine. The minimalistic nature of it kinda helped.
1:00, there, again. Chill down my spine. Although, the lower synth that is backing the melody in that part is almost inaudible. You want to isolate the two synths you use there.
Ending is very abrupt. Unless you added some echo or delay or reverb or all of those, and just let it naturally fade away... Because that is normally what happens to that end scratchy sound thing that you have used. And without it, people are just thrown back, like "what the fuck just happened?".
