Learn to move your feet, either by weighting the front and back to put pressure on the board to enhance your turn.
Lead with your leading hand toward where you want to be on the wave ( make sure you are also looking towards where you want to be). Often beginners swing their upper body and think they are turning ( not). Upper body wiggles only marginally effect the board without force through the feet! Learn to use your knees and ankle to drive the board. Best evidence of this is where your lean turn at the top fails, no drive through feet wave knocks the board from under you!
Learn to accelerate the board by putting down front foot pressure!
Your ankles are important tools giving you both front to back and side to side pressure and traction on each foot subtle control devices!
Upper body movement should wind force downward through the body, hips knees and ankles into the board to enhance power and traction driving the turn.
Your beginning elements are OK but your surfing is a work in progress ( as it is for us all)

Get someone on the beach to shoot you, the things you need to do will be more obvious!
