Pasterns look really long/weak, so that could hinder your horse's ability to stay sound under the strenuous sport of eventing. Like the above poster said, it is hard to see the photos because of the size, and the angles are not the best either.
Take pictures of the horse from the side standing square, and we can give you a more accurate critique :)
Every great dream begins with a dreamer. Always remember, you have within you the strength, the patience, and the passion to reach for the stars to change the world. ~Harriet Tubman
