Agree with Themacpack.
I will add this though.
The conformation of horses matters anywhere from very little to a great deal, and in some cases IS a deal breaker for certain disciplines.
Have you spent ANY time reading about horses, learning about conformation, and where faults may lie? That is the best way to learn, rather than coming to a forum. You need to study it more in depth than just getting answers from members.
And that means having pictures to look at easily, descriptions of the various things, so that you can reference them quickly and study them until you have them firmly in your mind.
You can also do some searching of your own by utilizing the search bar on your browser and typing in things you want to learn about.
Horses make me a better person.
