I think another way of saying what everyone is trying to explain is, to sink your body weight down thru your legs to your heels, as if your lower leg has weights attached. Will bring you closer to the saddle so you aren't so "perched" on your horse's neck, instead of moving forward so much with her when she goes over the jump. (trying to give a visualization, cus I always was the type to do better when visualizing things as I did them). You are looking okay I think, as you continue learning you and Love Story will get more "together" of course! :)
Love Story is a beautiful horse! Gorgeous! I want her! Lol, that is my critique for her, since I am not that good at critiquing horse ;)
