Well its kinda hard to critique her from those pics but it loks like she might be leaning a little too far forward at times. Although I do ride western and only read books on english so I may not be exactly right.
Not very good critiquing pictures but from what I can see the jumping is fine. She could turn her toes in a bit but other than that fine. On the flat she should turn her toes in and put her thumbs on top, lifting them just a tad. She also looks like she could be hollowing her back. Instead of sticking her butt out just flatten her back. Her pony is absolutely gorgeous.
Hi, I agree with Raini, toes in, thumbs up.
She does look to be nice and relaxed, critiquing pictures are normally best from the side, but they look good together, and the pony is adorable.
