I wouldn't mind to have seen a bit of a bigger hip on her as her shoulder is a bit larger than her hip and throws out that balance.
Because she's also butt high, it makes her underline look a bit over exaggerated. All horses curve up at the stomach, of course. I like to see them a little more even with less of an angle and smoother lines as well.
Here's a pic to compare, so you can see what I'm talking about:
And I'm not an overly big fan of her face... I do like my mares to LOOK like mares... a little more feminine would be nice.
However, there isn't really anything majorily conformationally wrong with her, and I don't see her having any problems performing in any sport due to conformation faults.
She's got a really nice angle to her back legs so she should be able to hunker right down and move when she has too. Plus she looks like she's a wonderful temperment. :)
