Due to positioning you cannot easily see it, but this filly is very down hill and butt high. She also is over angulated thru the hock and I suspect sickle hocked (enough to maybe cause a curb to develop). She is a bit slipper footed behind.
Her front is very nice. Nice shoulder and I think nice neck (position makes it hard to tell). Her back is a little long. Her croup is a little steep
She looks to have decent bone and her feet seem small and fine all the way round which may cause issues leaving her barefoot.
Lovely color and obviously well cared for.
A well kept 2 year old usually does not grow much more (especially this breed). I suspect you may make 14.3.. maybe 15hh on a good day. I prefer a well balanced small horse to a poorly conformed tall horse. This horse is the former and there is nothing wrong with that.
