I feel that this track did do a good job at re-producing the Nightkilla dubstep style: from the tiny piano, to the cooker bass. Kudos to you for getting those details!
However, I feel like this song is mostly copy and paste. The intro, post drop and outro are virtually the same as each other, and so are the drops tempo aside.
Something that could have made this song a bit more interesting could have been a half time drum pattern on the first drop for instance, or a Nightkilla style piano in the post drop, or maybe make the eerie sound more interesting on the outro by slowly covering it in reverb with an automation.
I hope these ideas help on your next tracks. Keep it up!
