One area that you can definitely work on will be your wavedashes and wavelands.
Regarding wavedashes, try to simply wavedash in a direction and then dash right after the wavedash ends. Imo, it helps to reset the stick after doing the wavedash.
You will notice that it's not easy to time the dash exactly when the wavedash ends. That's because first of all you need to be consistent in your wavedash timing (how close to the ground you are when you start the airdodge), and then you need to be fully aware of exactly how long your wavedash lasts. So try and practice that, internalize all those little timings and you will soon be able to move out of a wavedash more elegantly.
The same principles apply for practicing wavelands.
Those two things helped me a lot.
