she looke like either a gaited horse or a standard bred.
Her hip is very flat, which makes her look like she might in future become a bit sway backed. That can make for saddle fitting challanges. Her hindlegs also kind of hang out behind her body, and the fetlock looks like it nearly touches the ground in back.
These are things that look "off" to me, but since I am not used to gaited horses, and if she is gaited, they might be more typical of gaited horse.
However, as the others said, her temperament if really important, and she does seem to have good bone and a "go forward" attitde, which is really nice for trial riding.
