Pitching and One Piece Takeaway

Henning told me that he observed me while I was practising pitching... I thinned nearly every shot. Why? It could be a lot of different reasons.weight on the back, deceleration of club, too much wrist action. When he saw how I was pitching my hands were too much in front , thereby I shut the face of the club (from 52gap wedge would turn to 42 9iron). So we started to work on correcting these mistakes
First my takeaway was too wristy meaning I hinged my wrist straight away while starting the takeaway. It should be a one piece takeaway where I turn the club with my shoulder  and where the wrist hinge happens only towards the end of the upswing.
My hands and club (shaft) should be in line or behind the ball so that I can use the loft of the club and the bounce.
My weight should be on the front foot although the hands are more important as he showed while pitching on the  right leg.
And one should accelerate through the ball.
