Hey, that's actually a good song! Definitely feels spooky sometimes, but the last melody isn't exactly scary, but kinda sad ( I see you threw in some minor scale stuff). My guess is that the low end is intentionally lacking. Because of those kicks (?) in the beginning I thought that it's gonna be a trap song, but you just played with expectations of the listener. And it didn't make it worse, even better imo!
I gotta say, these melodies are pretty good, but they all carry very different moods. Don't try to layer a bunch of them, cuz sometimes less=better. But that choice is always up to you.
Once again, I wish you good luck with your work!
P.S. Sorry for the essay, didn't mean to write so much
