I agree with tinyliny completely! Get her into work, and she'll be quite the stunner! I'm not generally a huge fan of saddlebreds, either, lol.
Anyway, on with my attempt at a critique... I'm pretty new to this and still learning, so bear with me if I make any stupid mistakes, lol.
She has nice short and well-sloped pasterns, with round hocks which look pretty well set to me. Short straight canons. Her front legs are perfect- straight from the front view, not over or under at the knee, going into a beautiful shoulder with good slope. Her neck is a bit thick since she is overweight but it's a good length and looks to tie in well. Her withers don't look too high or too low. Her girth looks average, not especially deep but not shallow at all, either. She has a nice short back. She has a pretty short croup but that seems like a saddlebred thing to me. Overall she looks perfectly balanced to me throughout her body, she's lovely!
