She's not sickle hocked either... just stands under herself a little bit. If anything, she's a tad bit straight through the hocks. Typical halter QH/paint through the hind... which is not dreadful, but not ideal. Imagine that hindquarter with the massive amounts of muscle you see on halter QH's... yeah, pretty typical halter horse hind end.
I don't like her neck. It's not how thick it is, it's the shape of it.
She looks ok in some pics re her knees but definitely looks back at the knee in other pics. Those cannons are quite long in her front legs, and it looks like she toes out. I think she could definitely use a good farrier and perhaps some corrective trimming (and prayers that it isn't too late to correct any faults).
She's a wee bit long in the back, and a wee bit downhill.
HOWEVER, she is a nice QH type... I love a good QH! (just not a fan of their build for my discipline, but that's a different matter entirely)
A CLEAN SLATE FOR THE FUTURE
