She has a bit thick of a neck, smaller head, and no real chest. Bit steep of a croup and high set tail too. She does have a nice short back (except it does curve up a bit near her croup) and legs, decent confo, none of the above really aren't serious like leg "defects."
I think she has too small of a head and too thick of a neck. I don't really like the slope of her shoulder and she could use a bigger hip. She may be a little cow hocked in the hind legs but nothing at all serious.
Overall though, she's got pretty good conformation.
I am going to give this a try, she's shaped similar to my gelding.
Her neck ties in a little low to her chest.
She's slightly toed out in the the back.
The second picture makes her pasterns look little weak.
Same squishy quarter horse bum as my boy, he can really use it too! ;)
