Sort of. Not really. In pic 4 Kvitova is making contact where you should be which is between the head and the shoulder. OP is making contact to the right side of his body. Also OP is in full radial deviation there and the racquet is pointing almost straight up as opposed to Kvitova who is making contact in a more neutral wrist position with more angle between racquet and forearm for leverage. OP has a lot less leverage in his contact position.
