You have to bring your legs under you more, instead of bracing them in front of you. Its something that beginner or untrained riders often do. Its probably a fair bit comfier because your back is sort of rolled and your sitting on your bum instead of your seat bones. I believe that is how western riders ride.
With english riding you want to develop and independent seat, which means you balance on your own, riding lightly without inhibiting the horse and are able to give clear aids. Your aim is to have a straight line from your ear, shoulder, hip and heel. Try and ride with this line, for a while you might feel a little unsteady because you aren't bracing with your legs but once you can regain your seat you can communicate with your horse much easier.
Also, to me it looked like your hands were rolling so that your thumbs were facing each other. Make sure your hands are upright, with your thumbs facing up and forward. If you pull back with your hands like this your elbows will go out to the side and you will have "chicken wings". Also, because your arms cannot bend and relax you may find it harder to move with the horses head.
