Good racing, but 1 advice. You should shift with less force. In every race technique book they'll tell you that shifting shouldn't be forced but just smooth and not rushed.
It's also good to see you keep your hands on the wheel as much as possible, I see a lot of dumbasses on youtube who keep their hand on the shifter which basically half's your steering abililty.
So basically nice technique you got, but you need to work on your shifting a bit.
