Hi there Mickey and welcome to H.F. :)
Horse: I really think he is GORGEOUS and he looks very well taken care of. I really like that he is paying attention to you, in almost every picture, his ears are on you.
The Good: I like how you look confident yet gentle. I also like how soft your hands are on his mouth. The angle from your shoulder to your elbow to your hands to the bit is really good, but in the second photo you lost a little of that bend. And I really like your release in the photo of you jumping. Its soft, yet you still have contact and balance.
The Bad: Like Tinyliny said, I think you would really bebefit from putting your stirrups up a notch or two, there should be AT LEAST a 90 degree angle in your knee. I also agree that your legs look tense and that you should try to really work on relaxing your leg. I think that no stirrup work would really help you out. It also, to me, looks as if you're lacking some leg muscle, which would also be helped by no stirrup work. In the photo of you jumping, your back is pretty rounded. Your goal should be for a nice, flat back over fences. The rounding could be cause by tension and lack of muscle as well.
I really hoped that I helped you some :) overall, you two look very well suited together and very happy. Good luck!!! :)
