You are twisting too much toward the inside, allowing the horse to leak out through the outside shoulder. YOur horse is overbending and leaning out throught that shoulder, and you are actually "matching" that postition. you want to stay square over your horse. So, the amount of turn in your body should only match the arc/bend you have the horse on. I can also see that your outside elbow and arm are well off of your body, again, allowing, even encouraging, the horse to overbend and leak out through that shoulder.
Try anchoring your outside upper arm to your ribcage, and maybe even put that hand on the side of the wither to give a very steady oustide rein (make it a bit sorter), then use your inside rein to ask the hrose to just look to the inside of the circel and flex the poll /jaw that way , NOT bend at the base of the neck and through outside shoulder out.
Don't look SO much toward the inside of the circle, too.
