These are pretty decent overall. Biggest thing to fix is the fact that you're overdoing the "look down" cue, which is resulting in a lack of extension of your middle and upper back. Look at a spot 5 feet ahead of you on the floor. Keep your spine long and straight. Also don't be so intentional about leaning over. It will happen on its own if the bar stays in balance and your knees and hips travel in accordance with the model.
