The theme with music box sounds really dope (by the way - where do you got it from?), however to make it more trap-sounding I think I would check how would it sound if it would be detuned more. I also think you can try going through some other drum samples (808 - something with longer release & snare, hi-hats in terms of sound choice and patterns sound good), because they could hit even more. These are just my suggestions, generally I think your beat has cool mood and vibe.
