I don't care for that synth, the one that's like an electronic violin? That guy sounds better when he sings in a higher register, when he's singing really low, (at the beginning?) "it's creepy..." When he's singing higher, he sounds really good (to me) Hearing that synth oscillating wildly again, and still not liking it.
Overall, I like the song, it's very creative.
(please understand that anything I say may be and probably is wrong, I'm just giving my honest opinion)
