Looks fine to me, for jumping position. For non-jumping you'd want your stirrups down a couple of holes or so. The general rule is to just be able to see the tip of your toe when you look down; and your stirrup leather to hang straight down.
It could just be the angle of the shot, but on the first piccy the saddle looks too far forward.
I agree, in the first pic the saddle does look very forward on your horses shoulders but otherwise your position isn't bad. In the second pic try to give with your hands more over the jump.
