not bad for some one playing for 4 months well done. I can see a number of things that you can improve on but lets start with the most basic and most important.
I believe that the most important part of any golf swing are the grip and the posture, it seems to me that you can improve on your grip and posture by having a few golf lessons with a good pro. that is why your hand seem to take the club back not your shoulders, arms and hands working together. your posture / stance is the reason you are swaying instead of turning your shoulders / hips.
it is very easy to get lost with golfing jargon and learn from many different players but having a few lessons at this stage will help you for the rest of your golfing life!
I see a lot of players using £300 drivers and hit it 180 yards in the wrong direction. if they spend half of that on lessons they could hit an umberela straighter and longer. good luck.
