I love this synth you've made. I wouldn't really change it a lot, actually I'd appreciate if you'd tell me how you made it, cause Im searching this sound for quite some time now!
Anyway, what I would suggest for the track:
Make some variation in the synth (low pass filter, high pass filter, distortion build ups etc)
Also, add more of these synths together that wobble unsynchronised. That might make the track a lot more interesting, cause more things are going on at the same time.
You could even pan one that goes from left to right? The sky is the fckn limit.
Things I would wish in a song like this:
-gradually building a stronger snare
-adding hats
-adding more synths
-adding some fx
-making some variations
have fun! hope I helped you out right there
