Alright a couple things I see...
You head level changes from high to low to high again. Try to make it consistantly going down hill. (HOW?) By not leaning forward at the waist. That is where you are losing your height and you eye level.
Second thing that I see, is that your glove hand (left) is dropping and pulling your shoulders. Look at any of the videos on this website, and you will NOT see a single MLB pitcher pull his glove away from his chest...Many pitcher actaully keep their glove in front of their chest the entire time.
When you pull your glove away from the center of your body, you miss left/right.
When you pull your head off center (like leaning forward like you do), you miss up/down.
