First of all, let me say you're doing a fine job for one year's dedication. Good posture. There's a few things I have noticed, I'd like to start with your set up. You look pretty tense, I'd bet your holding onto the club with a fairly tight grip as evidence by how inverted and close to your body your left elbow is. Nothing kills power like tension. Your grip is very firm (meaning too much of your left hand is on top of the grip at address). You make a very, very nice turn away from the ball. That invokes distance, with minimal effort. I'd suggest keeping your right knee flexed to create torque, as you certainly have the turn to do it. Flexing your back knee may feel like its restricting your turn when in fact it'll harness more stored energy from your turn. At the top club is shut (parallel to the ground result of firm grip), as the club face should be parallel to your left forearm at the top. Nice release. You come over the top, and with your grip, i'd venture to say you're doing all you can to keep the ball from going to the right. Start the downswing from the ground up. Again, I must commend your nice turn, and general move. The grip and keeping your right flexed should help you get to the ball from the inside and on the right plane, resulting in more consistent golf shots! You have a great turn, and a powerful release.
