Been many many years since I did any serious sparing, and there are many on here that can give you much more and better advice than I. All I have it move your head more to make it harder for te other guy to hit you.
Best advice I can give is to post longer unedited clips. Unedited sparring and bag work. It's just easier to get an honest perspective. Spar against really good guys that you can't win against (not all the time) so they can expose the holes a lot easier and quicker than someone your level.
