This is actually really good for a beginner producer, ngl. One thing I would say is that the bass needs a little bit less "clickiness". Try adding distortion and ott somewhere in the effect chain for the main growl.
a lot of serum sound design (but not all) is possible to translate into AT, so watch some videos about sound design of your choice and you'll be making some good stuff pretty soon
you're definitely getting better, just need more wacky experimentation, try out merging stuff (if theres a really low sub) and putting a waveshaper on it
