I wont tell you any combo specific stuff since CSX is right around the corner, but a few things you need to work on:
Work on your microdashing, you dropped so many combos at j.D because you weren't close enough to your opponent, also take note that you can super jump to solve this problem too. Make sure you work on both.
Auto-piloting, I noticed you do this in your Makoto match, when you hit an anti-air 6A you always just did 6A > 5B > 5CC etc. you need to stop autopiloting and start hitconfirming. This will help no matter what character you play.
Also tell your Hakumen friend that he needs to learn how to disrespect Noel's Drive more, Driving on Hakumen is a terrible idea to begin with thanks to his Drives, and he let you have so many free rounds because he got blown up by d.6B.
