Well, I've always been picked up when my toes point outwards. Try and keep them facing the front. Don't worry though because most girls and ladies do that for some reason and I don't really now why. I can't really do it, but it takes a lot of hard work and pain, so I guess it's just general horse riding. I can't really tell in the first picture if you are leaning to far foward or not, but try to sit back a little, that way, you'll have more chance or you're toes pointing the right way.
Looks brilliant to me. Posture and everything! But are you jumping only one jump in that arena? Because I have been taught that once you're half way over the jump you look at your next one, even if it's to the side... If you google some jumping pictures you'll know what I mean as you'll see people's head turned toward the jump they are going to next, while they are in mid-jump.
Other then that! You;ll look fabulous and you and your horse look great together! Keep up the great work and remember that the things I have said are just the wau I personally have been taught, so you might have been taught in a differnt way, so if you have, then that's fine! Just saying what I know!
Good luck and Well done!
