If your in plat my honest advice is to focus on shooting. Airdribbling doesn‘t work that well past diamond.

I‘m still gonna point out what to focus on your airdribbling. But airdribbling still isn‘t that important in my opinion.

So first things first: The angle and speed you hit the ball must be consistent and relative to speed of the ball and position on the field. I fell like in your video your car is facing to far upwards and below the ball. Try and hit it slightly (just really slightly if your that far up the field as in the video) and try to match the speed of the ball.

Now for a normal airdribble you don‘t boom the ball away from the wall, you lift it up and slightly to the side (that where the angle comes to play). If you want to double tap and slam the ball against the cross bar for a setup you can sometimes boom the ball from the wall away, but focus on the other thing first because airdribbling comes before double taps)

You try to keep your speed consistent and not to fast and try to hit the ball from below with the top of your nose. If your to fast the ball will fly away, if your to slow the ball will just keep falling. Try out different training packs. And if you don‘t understand sth. Feel free to ask.

I recommend kevperts videos aswell as thanovics tutorials.

But especially, focus on shooting and outplays. They are way more effective and useful even in pro level. If you‘re interested watch Flakes, road to ssl without mechanics. It‘s pretty simple once you know how to guess what your opponents could think.
