Horses toe out natually to some degree. Lots of times the toeing out too much is poor farrier work. I personally wouldn't worry about it and let your farrier address it. Yes the neck is short looking to me. The heads aren't ugly. I don't think neither looks that bad. None of thoses pics are good for conformation except one and it's not enough to really tell. I wouldn't pay attention to half of what people say anyway.
