Nice vocal track! I like the effect you had with the higher voice harmonizing with you. The background music also sounds cool. Your vocal style here fits with the topic of the song.
What I'd recommend doing with this is developing the backing track a little more so it reflects the emotions of the song and changes over time - maybe it could even be a little creepier? I feel like your voice also gets overpowered by the backing track for most of the song; I'd say either bump up the volume of the vocal track or take the volume of the back track down a notch. Also try practicing singing with a tuner a little bit - you're almost there, actually! From my experience, singing with electronic instruments can be quite unforgiving because of the very pitched nature of a lot of computer samples.
Can you put the lyrics in the description, by the way? I'd comment on them, but I can't quite tell what they are.
