She looks very butt high in that first photo, though it may be the angle of the photo. Also, it's hard to see her shoulder underneath that lovely mane. I'd take a new pic for any ads. The second photo is much better for judging conformation.
I don't see any glaring faults, maybe a slightly long back, steepish croup, but will check back to read what the experts have to say!
She has lots of famous names in her pedigree. I'm not certain, but is Doc Bar associated with some genetic condition?
What I like about the pedigree is that it is balanced with both the male side AND the female side solid all the way back. The female tail (which is often where a weak pedigree shows up) goes back to solid lines... and the doubling up on doc bar AND Peppy San breeding might give you some "cow."
I wish her hocks were lower and her butt better muscled.. and her entire hind quarter placed a little further forward. She is downhill, but for cutting that is not so bad a thing. She is a lovely bay. How tall is she?
No idea current prices, but this is a horse I would not mind owning and if I did I would be wishing I still had my cattle.
Also, she has been pretty level most of the time, just going through a growth spurt it seems. I don't expect her to be perfectly level, however since the picture she has leveled out more, and is starting to fill out. Id say she is about 14.2 right now.
