She looks like a pretty girl :) But she really doesn't have the greatest conformation around. For starters, look at her haunches. They are higher than her withers, which is undesirable in any discipline, and can make it difficult for the horse to perform. Her chest isn't very impressive, either. Her neck is a bit short, and her throatlatch looks thin and sort of gangly. Her head looks too big for her neck, but I like her eye. Also, she has an awful parrot mouth.
She's only three, so things could change... But for the most part, I don't think they will. She isn't the most desirable speciman for you by any means.
