This is a pretty neat track overall, there are just a few things I'd look at altering..

Firstly, the piano-y sound you use to do the main theme at the beginning just sounds a bit amateurish on its own, and it lacks in any depth or imagination, I'd probably chuck another layer on top to help develop it a bit. I really like the bite of the drums in this part though. The build up is a bit too weak ... More and obvious for my taste as well, so perhaps I'd work on that too. The drop is pretty solid to be honest, despite the sounds being a bit generic and excessively dirty in some cases, which makes it sound a tad fragmented at times. Similarly, the levels in the drop aren't particularly sound, meaning certain components of the synths and drums get lost sometimes, so I'd re-evaluate and adjust the mix as a whole, which should bring a lot more energy to the mix.

But generally, I think you have a very good foundation here, with no massively resounding issues!
