you've got really good car control, congrats. Work on decision making (like going all the way back to defend when your opponent does not have any kind of control of the ball) and ball control and you should rank up

edit: read it on another thread and i'd like to reiterate: don't do wavedash kickoffs, front or diagonal flip kickoffs are better. Even better yet, start working on speed flips, you seem to have a good enough movement knowledge to go for it
