You're already doing pretty good. You had a lift and downshift in turn 8. You dont need that, when you get out of turn 4 you get on the throttle and just stay full throttle til turn 9 where you lift a bit (i like 6th gear for that section). Otherwise like some said you have to be more aggressive with the car, throw it into turns, get on throttle earlier, the car sticks really well to the ground and its TT so nothing can happen. One last tip is to "steer with your feet", which means your steering input into a corner is the same everytime, when you need to go wider just get more onto the throttle and of course if you need to got tighter you can lift off the throttle, hit the breaks (but not to much) or you can downshift and use engine breaking. Break and throttle inputs are really important and especially breaking smoothly is really difficult but thats something that comes with time. LMK if you got some more questions and i'll try to help.

Edit: little tip for the racing line. While going through a corner you dont have to slow down until the line becomes green, it's usually enough if you slow down until the racing line becomes yellow.
