I sort of zoomed in on the shot of her conformation, but the video wouldn't play for me :( - what would you be wanting to do with her ?
From what I can see she seems relatively well put together, she is a bit downhill (as many ex racehorses are), her shoulder slope seems quite steep - but she seems to have a long humorus which gives her an open angle, her neckset is quite high, and the neck itself could use some work to shift the musclature a bit, it seems a little on the shorter side. I think her back length is lovely, she does lack a bit of loin girth and her loin looks like it might be a bit long, her LS seems a little further back than we'd like in a riding horse, but it isn't terrible. She appears to have adequate pelvic length, but she might be a bit shallow in angle and possibly a bit post legged. (Now, I did zoom on the photo, so everything is a bit fuzzy so all of this is a "best guess" )
Overall she's a nice looking horse.
