The bad: Her shoulder is kinda straight, but that's common. Her pasterns look a little too straight and her head isn't very refined. She looks a little cow hocked in the back.
The good: She has a beautiful color. I like how she's put together, she appears balanced and looks to be an excellent working horse. Nice back (not short, but not looooooooonger than a locomotive). Nice butt, doesn't have a short little neck or a super long one. Seems just right, I personally think it ties in well.
Overall: If I was looking for an intelligent ranch horse ready for long hours on the trails, or just something to enjoy and have fun with puttering around, she would definitely be a top choice. Not perfect, but in my opinion well made nonetheless. I like her color and she seems pretty laid back. Doesn't have a rat tail (I hate rat tails on horses), but I would either pull or hog her mane. She looks like she would also be a fun little playday horse.
At $400 I'd consider her an excellent buy with plenty of potential.
Wait! I'll fix it....
