Generally, I like her!
I think she stands a bit too far under herself on the front end, I'd like to see a bit more development in her hip, but she's young yet and that'll come with more riding, and I think her face could with just a touch more of a feminine look to it (I may be biased here because I am a Arabian breeder and Arab mares always tend to look more feminine than any other, I think).
But, she's a really nice shoulder, she looks like she's really well balanced, and she does have a nice head. The distance between her eyes and her nostrils is good, a wide set between her eyes, and she's got a LOVELY tail set as well. Good length to her neck and her throatlatch isn't too thick or too thin.
And, you may think I'm a bit crazy, but she's got three socks so she must be an excellent horse. Most of my horses have three socks, so I take that as a good sign.
I think you've got a lovely girl there. :)
