Her shoulder is a tad upright for a dressage horse, close to ideal for a jumper. She's a tad long in the back, and her croup is a little prominent. A wee bit downhill but being 3 she may grow out if it. Her cannons are a hair long but not too bad for a TB, and I like her hindquarter but I feel like her stifle angle is a tad open (in other words that's a slightly posty hind leg). Lovely deep heartgirth, she might be a bit wasp-waisted which would make her weak through the loin but if she's fresh off the track she might let down.
I won't say anything about head/neck/tie in, because of the angle of her head it will change the apparent proportions.
Overall I really like her, but not for a dressage horse. I think, provided she levels out or matures uphill, she'd make a great jumper... different types! Usually, a good jumper should be able to offer a decent dressage test, and a good dressage horse should be able to jump ok, but there's a reason the types for top jumpers and top dressage horses are completely different. Different horses for different courses.
I love her, but if you don't jump, you should be looking for a horse with a slightly shorter back, more slope in the shoulder, and a smoother coupling.
