First you need a book on taking conformation pictures if you are going to ask for opinions and get a trained eye looking at them .
I need to ask some questions: age, height, what has been done with this horse recently, is she broke to ride english or western?
You need a true side view shot not something that is off by 25degree angles. Search amazon
and find a book on conformation pics.
Here is what I see but might be the pics , lighting and your angled shots:
Topline: longer back to neck, croup angle too severe, top line needs muscle and you will need to work that in side reins or pessoa rigging,
Might be even structurally downhill but with muscle might improve
Legs: camped under in the front..will give a choppy ride possibly
Pastern angles are off because her feet are poorly trimmed and incorrect angles to hold this poor gal. More muscle definition in front than back and might give a clue she is using her front end more than engaging her hocks and lower back... check out her lower back to hip and hock area.
hocks are slightly higher in back compared to knee joints unless she is standing on a sloped surface.
Slightly you necked but might be lack of muscle and again has to do with her poorly defined muscle tone but she might also be defensive and hollow when she is under saddle.
Shoulder angle is acceptable depending on what activity you want to do with her.
She appears to have no wither or is mutton backed but once again may be pic angles. Might be a consideration regarding saddle fit.
I do love her coloring, her tail is beautiful but she might be a bit tenative regarding new issues as she does have a slight "bugging eye"
I'd really be able to give you more if you had a video of her and we could comment on her self carriage and watch her wtc.
