Not badd, but you went too low especially when swerving left and right. Come from a medium height then adjust, like a rocket and spin
4 at the most, not much skill involved all you did was hold L1 and flip it around while boosting towards the ball, not enough height for it to merit above a mark at 4/10, not too bad but if this is your best goal I'd deeply consider deleting the game if I were you
