I couldn't agree with Jag6201, your leg is so far back, your upper body is suffering from it. You need to be deeper in your seat and roll your shoulders back. But your lower leg is keeping you from that. your stirrups look a tad short, try lengthening them a whole and sit back more in the saddle. otherwise, you definitely are progressing!
