I am going to be honest, I have only ridden western a few times so I don't really know too much about it. In the first western picture your upper body was too forward, but that was fixed in the last picture. Also your hands are supposed to be nice and low, but this also was fixed in the last picture. :) Bareback (waist down) I think you could be sitting an inch or 2 farther back. If you ever needed the brakes you wouldn't be able to do anything, because your hands are literally right in front of you. And if you ever tipped your toe up you would trip your horse (this I have done and I almost went flying). Bareback (jumping) I think you could tip your toes up and use your calves to help keep your lower leg in place. Otherwise your release is good, and your off of his back. You improved quite a bit in a year, you should be proud of yourself.
