You look very good on the flat. The only things I noticed is that you're looking down in the second pic and also it appears that you have puppy paws, especially in the first pic.
For jumping I know this was already said but please, please don't use your dressage saddle for jumping. It was not designed for that and could damage your horses back. As for your position you need to bring your leg forward and also give more of a release. Also, it looks like your toe is turned too far away from the horse's side. On the other hand your back is nice and flat and you are looking ahead.
Good job and keep up the hard work.
