My judging skills are very rusty at best...been more than 20 years since I had judging education from BHE.
I will do my best in judging her if I was a judge but only with pictures, there are some sight adjustment you would need to make then I can make the next judgement there. No motion displayed here either LOL.
She is a red roan, thats for sure. Looks more QH type. Takes more of Sonny Dee Bar white traits....
HEAD: Her bald face or face markings with alot of white would take away alot of her femine traits. Without a good clipping job, she has alot of "boy" looks about her and large jowls with wide throat will thin down with exercise. Eyes are not large, rather small for a QH but it coudl be due to her relaxed nature displayed in the picture. 
NECK: thick and short, does not balance the rest of the body but acceptable for riding pleasure horse.
SHOULDER: Nice slope
BACK: withers are a little flat and top line is a little low where the saddle sits...probably due to her age or the angle of the photograph.
HIP/CROUP: hip is a little steep instead of rounded like a QH....again, it would be the way she is standing or the angle of the photograph.
BODY: well put together well defined girth (with a pot belly LOL). With exercise, she will tone up and good well in those areas and define more muscles in her forearms.
FORELEGS: nice, looks little toed out and short pasterns
HINDLEGS: due to the way she is standing, looked sickle hocked or "under" the body. Point of hip does not line down with the hock to pastern.
All in all, she looks like a very good pleasure horse and once she gets all neat and in condition, she would look ten times better. If you are intending to use her as a riding horse, then conformation would not be the strongest suit but to look at some faults to see if it would help or jeopardize her riding career such as jumping, dressage, versatility and English Pleasure. IMO, I would not use her as a broodmare. It would be best for you to get someone else to visualize her to make sure she would "fit" your needs as a riding horse. By photo alone, you can not get that disposition and personality thru photos in most cases. Some of the most beautiful horses you would think he would have a superb personality is a devil in disguise!
