I haven't worked with many gaited horses and as such, am somewhat ignorant about breed standards, but regardless, you've got quite a nice mare there. Judging by the pictures you have up, her neck is set just a touch low, her head's a bit coarse, has a slightly thick throatlatch, and may be cow hocked, although that could just be how she managed to stand in the photo. As for her good points, it looks like she's got some big, sound feet (I think I like your farriers work!), is well coupled, has a nice angle to her shoulder, good pasterns and smooth joints. And her coat is a georgeous. I definitely like her, she's really looks like a very nice mare.
