Driver swing help pt 2

So last week I got some really good help from the group in relation to my backswing (which hopefully looks okay in this video). Still a long way to go but it’s much better so thanks to those people.

I am now really really struggling with my downswing though. I know I’m jumping at impact and there’s some early extension, but I really don’t know what to do with the club to get it down to the ball correctly and what to do with my body.

Any tips, tricks or drills would be very much appreciated.
