First off, howdy and welcome to the forum
It's so hard to judge accurately on a weanling because they can go through some really wonky growth stages LOL.
What I can see is that it appears her head is rather large or her neck is really skinny...maybe both are true and make each other look even worse LOL.
Other than that, I really don't see much of anything wrong with her. Of course, she's drastically downhill right now, but she'll grow so I have no idea how much she'll even out.
Her legs, for the most part, look straight and strong with good angles. She's standing camped under pretty bad right there, but it's only one picture so I won't call it a fault yet. I can't see her front hooves so I can't judge them.
Did they try to roach her mane or has she just not grown one yet?
