it seems that you pull the club head behind the line of your feet in take away, which suggests you use your hands to take the club back, try to take the club back so when it is half way the club head is outside your hands and parralel to your target line. your leg action and shoulder turn in your take away are not doing much, try to take the club back using your arms, hands and shoulders. another suggestion would be to take 3/4 back swings, you dont need a full swing with an iron.
hope this helps.
