That's not a bad start,eventually it will come naturally and you'll be confident in the hunt/stalk etc and so become confident in your shooting,another tip which may have been mentioned or seem obvious but thought I'd mention is watching an animals body language and use it in your stalking,ie,take a step when the head is down feeding then wait a second to make sure the animal is still unaware,using cover as much as possible til your within your range then let fly and pop! Another meal!!
