I like her head, but her throatlatch is a little thick. If you decide you want to show her (esp in halter) I would sweat her neck, then she'd have a really nice neck/throatlatch. She does look like she has a slightly larger jowl, but that may be all her fuzzy hair.
I think when you get her feet done her pasterns won't look so bad, but right now they look really long and sloped. She has a nice flat knee, and her hip isn't too bad.
It's hard to tell because of the strange pose you have her standing in (that's not how you set up a halter horse if that's what you're trying to do), but her shoulder looks a little steep. But it might angle out nicely if her head wasn't being held up so high.
Although she's not set up to show off her conformation correctly, she has a nice short back that will fill out and fix the dip in her croup with proper feeding and nutrition.
Her tail looks like it's set a little low, but that may just be an illusion because of her back looking so thin and sunken.
I looked at her blood lines, and she has two ties to *Bask and one tie to Raffles. But that's about it. Neither one of her parents are big. But that said, breeding doesn't make the horse.
I like the look in her eye, and I'd love to see pictures of her when she gains weight and sheds out all that hair. She's a cutie.
