Keep your head still, your back swing should be slow, as an amateur you should not take the club all the way back as most amateur's can't control the club at that level, act like your in a barrel and don't want to hit the sides of the barrel when you swing, your feet at the same distance apart as your shoulders, your grip as though you have a bird between your palm and the club and you don't want to kill the bird, don't slide your hips but turn them. These are just a few more of good techniques you may want to consider. Play well.
