Yes, you have correct lines, but you are twisted in the saddle, looking down and pulling.
I am not going to use a picture of myself as I do not ride hunt seat, but a quick google search popped this young rider up. She is relaxed, sitting up straight and is resting her hands so they don't interfere with her horse. Her ankles are flexed down and her leg is lying flat on the horse's side. She overall gives the appearance of balance and harmony.

The purpose of correct equitation is very basically to teach the rider to ride the horse without relying on it for balance. You appear to rely on your reins and crotch for balance. A very good exercise for you to do is to get your coach to lunge your horse with you riding it and eventually get so that you can ride in all three gaits without reins, or stirrups.
Good luck!
