Not the best pictures for critique because her tail (which is thick and rather lovely) is covering the shot of her legs from the hind and she doesn't have all four feet on the ground in the side view shot.
However, from what I can tell she doesn't have any glaring faults. She looks like she may be a little sensitive footed on the rocks though?
If you're looking for a kids horse, conformation comes after disposition and training in my book. I will take a pigeon toed, long backed, jug headed, pig eyed, ewe necked Thoroughbred that's completely bombproof, tolerant, and sweet over a stunning horse with flawless conformation that's girthy, and untrustworthy. A safe horse is priceless (no matter what they look like) when children are involved.
She does look sweet though and cute to boot.
If you post better pics I'll give another critique though.
