Critique my Mare

Just purchased my first reining prospect. She's a 5 yr old QH mare originally off the Babcock Ranch. She's had about a year of reining training already but was bred last year so needs to be legged back up and finished. I've attached a few photos. I know they're not the best but I'll work on getting some better pictures of her.

Here's her pedigree if anyone's interested in seeing it. Rubys N Rhinestones Quarter Horse

Wow! She's a looker! Amazing bloodlines to boot, too! I'm not a pro with reining horses, but she looks like a top quality Reiner if you ask me.

Thanks! She's great! Has the sweetest disposition too! :)

She is beautiful!

She is a very lovely mare.
I think the flaws that would stand out to me are, in the first picture she appears to have a minor roach. She does have a long back, she is over all long. She has a very nice head, nice high neck set.
