First, your back leg seems unstable when you push off, which likely means you are not loading the back foot enough, you want more like 60 to 40 or 70 to 30 on the back foot. Second, your racquet drop looks limited because the palm and shoulder lock up, which reduces pronation and power. I also suggest adjusting grip to confirm it is continental, and taking contact a little higher and more to the left. I asked you to work on one thing at a time, and I requested you check out my plugin."}
