Your knees coming in is also not a big deal. Focus more on getting them out.
Your biggest issue is it looks like (though impossible to say from here) you are craning your neck upwards throughout the rep. Look down. This is causing some secondary "looseness" throughout the rep. Fixing this will fix that.
