I don't have a lot of time but I'll try to throw my $.02 in.
First row, first picture: I'd like to see a bit more energy from the horse. If this compromises a pretty head set, that's ok. We want to focus on the quality of the gait above all. That said, a bit more energy- looks a bit heavy on the forehand. Not much though. Also, I'd like to see you bring your leg back a tad.
First row second picture: Very nice; body position. Both horse and you are very straight and forward. Very good.
Second row first picture: A bit tense. Could use relaxation without losing forwardness.
Second row, second picture. Again, very good. However, you have drawn your leg up. Stretch your leg and your position will better.
Third row, first picture: Very good bend all the way through the body. Just be sure to maintain contact with the outside rein. This will keep the shoulder from popping out, the horse bending with it's nose rather then body and only your inside rein creating the bend. I'd also like to see you sit straighter. Stretch your legs downward and turn your shoulders with your horse's shoulders. You seem to be a bit off center of the horse's back. I may be wrong. It is easy to be thrown off center in the circle when trying to bend. If needed, place more weight on the inside stirrup.
Third row, second picture: Already mentioned - straight out a bit. I can't tell the height of the jump but you may be close to over jumping.
Forth row, first picture: Very very good. The only thing I can really comment on is bringing your leg back a touch, thumbs upward and look up. The horse is forward yet relaxed. Be careful, he looks to be going slightly under the vertical, but not enough to cause great concern.
You are an excellent rider. I look forward to watching how you progress.
PS Was this at a show?
