She was probably referring to her shoulder. Andalusians can sometimes have quite upright shoulders compared to the sloping shoulder say that some TB's have and that contributes to a different way of moving.
Mine is a foreign breed too. He is a nice horse with reasonable conformation,and usually goes well, but I know if I go in an english class - riding horse or lightweight hunter - I only go for the outing, I know we are going to be at the end of the line as he is just too "different" in type and doesn't fit with what the judge will be looking for. If you enter a show ring you have to get used to the idea of coming last as well as first, because it is that judge's opinion on that day and not every judge likes the same thing.
Yours is a lovely horse, don't take it to heart, it is only one show and one judge. This is showing, you just have to loose graciously and look forward to another day.
"Too upright" may be in relation to the slope of the shoulder, or it could be in relation to the slope of the pastern and hoof, which should ideally be around a 45 to 55 degree angle. When looking from the side the pastern should roughly follow the line of the hoof (when trimmed). The angle changes slightly as the hoof gets longer, so for showing its important to keep your hooves trimmed. If you look around at different horses on your yard you'll see how the angle of the hoof and pastern differs greatly from horse to horse.
Say it like it is. Your horse isn't the right stamp for a proper riding horse. It's too thick set, heavy and hairy for a start. Secondly, from the pictures it does look very upright in its limbs - shoulders and hind legs in particular, which would mean it had no reach when moving and would be a very up and down ride rather than a smooth ride.
I'm sure it is a lovely horse and at local riding club level it will do well as it is very pretty. But take it out proper showing and you won't even get a look in I'm afraid, no matter how well behaved your horse is.
Judges also aren't impressed by how many championships or classes your horse has won previously, they judge what they see on the day. They have an image in their head of their ideal stamp of each section and their winners will be the ones that match that as closely as possible.
Everyone whinges about showing, why they didn't get placed when they thought they deserved to, when they get placed when they know they didn't deserve to but at the end of the day you are paying for someone elses opinion of your horse and if they don't like your horse they won't place it. Simple as. Everyone thinks their horses are marvelous and they can rarely see the faults in them themselves, just don't take it out on the judges when you don't get the result you wanted or thought you should get.
Hope this helps, not read all the replies but at local level I would not be too bothered.
(iii) Riding Horses
A Riding Horse is between a Hack and a Hunter. It should have quality, substance, good bone, correct conformation, presence and true action. Horses may not be registered as Riding Horses if they have been placed 1st, 2nd or 3rd in any ridden Hunter class at the Royal International Horse Show or the Horse of the Year Show in the current
or previous year.
Riding Horses can be:
Small Riding Horse mare or gelding four years old and over, exceeding 148cms and not exceeding 158cms.
Large Riding Horse mare or gelding four years old and over, exceeding 158cms
The Association recommends that shows, if possible, should hold classes for both height categories. If there is only one class held it must cover the full range of heights and the wording should be as follows:
Open Riding Horse mare or gelding four years old and over, exceeding 148cms.
For Novice, Ladies Side Saddle, Young Rider, Restricted, Amateur and Amateur Owner Rider classes see Rule 7
(Definitions and Classifications).
Riding Horse Judging to be judged on type, ride, manners and conformation. Judges should ask the class to gallop (conditions permitting). Judges must ride the exhibits first and then may require individual shows from as many as time allows. The individual show should not exceed 1½ minutes and should include walk, trot, canter, gallop, rein back (optional), stand still and obedience to the leg.
