I think you two look awesome together.
Aside from being a bit too far forward in some of the jump photos, looking down alot, and having too much bend in your wrists, I think you are looking really good.
Your horse has a really nice jump. In the one pic he has taken off a bit too early, but this can be fixed using jump\trot poles in from of a jump to give him a better idea where he can take off from. It will also help you visualize where he should take off, and you can adjust your seat position to help him reach that spot.
In the flat, he does seem to occasionally lose his drive from behind; in the trot pics, he looks fairly decent, but in the one where he is cantering, he is definitely leaving his hindend behind, so to speak! He should stay rounded right up to and over the jump. Really concentrate on where you are sitting on him, and balance your weight differently if he seems to move his power to the front end (sit back on your seat more, to encourage him to drop back to his hind quarters). Half halts can help in this area as well, as it gives him a chance to rebalance himself, and get his rear drive back.
