I just wanted to critique your jumping position if that's OK? I have noticed that you are leaning a little too far forward and just about laying on his neck. This puts alot of wieght on his neck and front end(even though he is a pretty jumper if you sat back a little more it would make it easier for him). If you look at some of your pictures you can also see that your legs have slipped slightly forward and you automatically did that to help your leaning forward. If he happens to stop abruptly than I bet he will kindly let you go over first lol.
Also if you look at your flat pictures you can see that you are almost always looking down. Are you looking for the correct diagnal or lead? Remember that they are the horses feet lol and he should be concentrating on where they are placed. This again will also help his balance if you look up. Remember to also keep your thumbs on top.
Overall you look like you have a solid position with just a few little tweeks. I love your soft hands and you nice releases for the jumps.
I hope you don't mind me critiqueing you! I just like to help people be the best they can!
Have a good one!
PS Beautiful horse :)
