Hi i am very new to this forum and am a little daft when it comes to computers so bare with me.
Also the outfit is gorgeous!!
i have done quite a few vet checks over the years and can tell you that there is no horse with a 100% perfect vet check score if you are picky. it is also very hard to judge a horses confirmation and performance from a static photo. What you do with him is also important. slight cow hocks/toe out can be a good thing in a heavy harness horse as they help traction of the hind legs and provide power. So confirmation faults can depend on the horses use.
i think that he looks a good type. he is a little upright in the pasterns and shoulders and a little straight through the hocks and stfles.
he looks a little toe in in the photos but without looking front on and able to compare the angle of his frog with the line of the pastern and the cannon it is not realy possible to say.
appart from saddle fit the high withers should not be a concern - unless you ride bare back a lot - ouch!
The pictures make him look a little long in the back and a little weak through the croup. (could be stance or muscle fitness) All in all though nothing that would have him breaking down. As far as confirmation for the show ring i am not a judge- i tend to look at the horse from a functional point of veiw rather than solely aesthetic. i also tend to like a chunky old fashioned head so get laughed at by my showy friends.
i would love to see him move - he looks like he would have a nice powerful stride and cover the ground well.
also the copper and zinc should do the coat wonders. sometimes a omega 3 source like flax seed will help as well
