These look pretty good. You do need to lean over a touch more right from the start of the descent. In the bottom things sometimes get a bit wonky. Part of it is likely your "tubows." I'm not sure you need them at this point, but if you do, I would step back away from them an inch or two. It looks like in some reps your knees aren't getting quite forward enough and this might be because the tubow is telling you that you are close enough. I would address these first and then see what the ip drive is like. For the reps here were you could have a bit more hip drive, fixing these areas may take of it.
