Eek, he's a bit of a trainwreck! Now bear in mind I'm not a big fan of Friesians to begin with, so it takes a pretty spectacular one for me to actually like it, but looking past that at the conformation just makes me cringe.
He is downhill, extremely long in the cannons, I don't like his back end AT ALL, that neck is just... ew... and that shoulder is not a dressage horse shoulder.
This horse is built like a poor example of a cart horse. He is not, conformationally speaking, a dressage horse. However, that isn't to say he couldn't do low level dressage. I just wouldn't pay big money for him.
