I can see loads wrong with his conformation- so much so I'll send you Duffy with her pigeon toes to show you what a REAL dressage horse should look like..
Nah, I'm kidding.
He has such a handsome face, and got that 'look at me' sort of thing... and that's from stills!!
I reckon he could do fairly well in jumping.. maybe its just me but his back is shorter, rather than too long, so could do well in it! My old horse had a looonggg back, and had to heave over any jumps. But your lad, oh my, he is stunning.
OH, and Kayty, unless you want me to curse Billy to make him 15.1HH he's mine
