To me she is short in the neck, Thick through the jowl, back at the knee and sickle hocked.
The big one to me would be the back at the knee. This puts massive strain on the tendons of the front legs and makes it more likely for the horse to injure its tendons. Far better to be over at the knee.
Short neck and Thick through the jowl is a typical draft thing, will only realy affect you if you want to do dressage or to ask the horse to flex at the poll since this will be quite difficult for the horse
She doesnt look downhill to me, I think that is an optical illusion because her back end is more developed then her front.
