She’s pretty! 
To me it looks like she needs topline & muscle over all
My Ottb looked similar to her when I got him, took a few months for him to get topline and muscle, on the right feed and supplements.
some exercises I used was pole work..
W/T/C over poles, I’ve done figure eights, pin wheels, switch backs, bending lines, bending bounces massacre, figure 8 bounce, serpentine, ETC. They all seemed to contribute.
I also lunged him over jumps, he’s free jumped 3’ft but I only lunged him up to 2’ft.
Once my TB got weight and muscle, he looked stout. She might end up having more of an athletic build rather then a more stout one? I don’t know tons about builds, so I’ll let the others tell you.
She doesn’t have ulcers right?
I wish you luck!
