The only 'flaw' I saw was that she seems to be a bit toed out in the back. Nothing terrible but enough to notice. I don't think she is sway backed in the traditional sense. She just has the right combination of Big Bum, Shark fins and a hay belly. That always makes things look worse. She doesn't look nearly as bum high in the after pics as the before. She sure is gaining muscle though!
Now on to the good! For a horse that will be used, she has great pasterns. I love the angle and length. She's probably pretty fast for a little thing! She's got a nice big shoulder to balance out her big bum. A smooth looking shoulder...how is her trot? I would imagine it would be much better than some of the other 'jack hammer' ponies!
She's got a very cute face...and that sure doesn't hurt!
